OSX Developer System installation
This guide assumes a fresh install of Mac OSX 10.7 Lion.
Create the a User called "brew" and check "Allow user to administer this computer". Open a console as brew or switch to the brew user using
sudo su - brew.
Install Xcode and the Command Line Tools from inside the Xcode Preferences. (You can use the App Store to install Xcode)
Follow https://github.com/mxcl/homebrew/wiki/installation to get the basic setup up and running. (the default, not the alternate installs).
Don't forget to install the requirements (Xcode, X11, Java Developer Update) mentioned in the installation guide.
Please note the recommendations below.
Installing as root is not recommended by the homebrew authors. But I hate nothing more than accidentally installing a
python package globally when I forget activating a virtualenv. To prevent this I decided to create a dedicated user
brew who has control over
/usr/local/. So for everything brew related and to install global
python/ruby/whatever packages it is necessary to
sudo su - brew.
python and stuff
brew install python /usr/local/bin/pip install --upgrade distribute
homebrew sets things up so that all packages installed via
python setup.py install,
get their commands installed to
/usr/local/share/python/ by default (see the above link for an explanation). So the
first rule of business is to add that path to your
PATH. Also if you want to use your homebrew python (and other
homebrew stuff) by default,
/usr/local/bin should be all the way at the front of your
If you decided to make a dedicated
brew user, do this for this user as well.
~/.profile (I recommend
.profile because it works in
PATH=/usr/local/bin:/usr/local/share/python:$PATH export PATH
remember to open a new terminal or call
source ~/.bash_profile in all of your open terminal windows to get

PATH changes worked and you are using the correct version.:

pip 1.1 from /usr/local/lib/python2.7/site-packages/pip-1.1-py2.7.egg (python 2.7)
install some dependencies:
brew install libjpeg brew install lcms brew install libtiff
If you don't need FREETYPE support, the regular
pip install PIL will work. There is no real need to install PIL
If you need FREETYPE, choose one of these three options. I recommend PIL with patching setup.py:
PIL with patching setup.py
Since PIL is not packaged correctly, setup.py needs to be tweaked.
Use the newest source version of PIL from http://www.pythonware.com/products/pil/ , download, upack and edit
FREETYPE_ROOT = ("/usr/x11/lib","/usr/x11/include",) in
python setup.py build_ext -i python setup.py install
This method has the advantage, that other packages that have PIL as a dependency will detect that it is already installed.
Pillow is an alternative Distribution of PIL:
pip install Pillow
Pillow does a great job of finding all the dependencies it needs in OSX. But it sucks a bit if an other packages list PIL as a dependency, because Pillow will not be recognized as a valid PIL installation and PIL will be installed again.
PIL globally with homebrew
Homebrew has a formula for PIL:
brew install pil
This may produce the dreaded
AccessInit: hash collision: 3 for both 1 and 1 error if some apps import PIL
from PIL import Image and others as
Some python packages don't work when PIL is installed with the
PIL prefix. Add a
PIL.pth file in
/usr/local/lib/python2.7/site-packages/PIL.pth containing the string
PIL. Now both
from PIL import Image and
import Image will work.
This oneliner will do exactly that:
echo "PIL" > /usr/local/lib/python2.7/site-packages/PIL.pth
use this version: http://bitbucket.org/2degrees/aggdraw-64bits/src
this needs mercurial to be installed (
pip install mercurial)
mkdir ~/tmp cd ~/tmp hg clone https://email@example.com/2degrees/aggdraw-64bits cd aggdraw-64bits /usr/local/bin/python setup.py build_ext -i /usr/local/bin/python setup.py install
Enabling freetype does not work for me. Please share if you find a way :-)

On my machine brew did not link
/usr/local/bin, so I had to do it manually. This is probably a bug homebrew and is likely to be fixed soon.:
cd /usr/local/bin ln -x ../Cellar/mysql/<mysql-version>/bin/mysql_config ./ pip install mysql-python

creating a spatially-enabled database template:

Creating a new database based on
createdb -T template_postgis [yourdatabase]
Alternatively it is possible to enable spatial functions on a existing databases by calling the above commands for
createdb, of course). Just use your existing database name instead of
brew install libmemcached
brew install spatialite-tools
brew install solr
brew install rabbitmq
set up a virtualhost (repeat for each app):
/usr/local/sbin/rabbitmqctl add_user myusername mypassword /usr/local/sbin/rabbitmqctl add_vhost myvhost /usr/local/sbin/rabbitmqctl set_permissions -p myvhost myusername ".*" ".*" ".*"
Add correct userrole:
psql -s postgres alter user postgres with role superuser;

Installation of the mercurial 2.1.1 package from pypi does not work.
See http://mercurial.selenic.com/bts/issue3277 for details. Until
2.1.2 is released I recommend downloading
the source and running
python setup.py install.
I had problems installing mercurial with pip on a 32bit MacBook Pro (Core Duo and less) because it failed to compile
the 64bit version of the mercurial.base85 extension. So I downloaded the mercurial 1.8.2 package from pypi and
-arch x86_64 near the end of
setup.py and the ran
python setup.py install and it worked fine.
