OSX Developer System installation
This guide assumes a fresh install of Mac OSX 10.6 Snow Leopard or 10.7 Lion.
Create the user "brew" with the Standardpassword. Open a console as brew or switch to the brew user using
sudo su - brew.
Install Xcode and the Command Line Tools from inside Xcodes 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)
On a completely fresh Lion install I had to use
/usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/1140207)" for the initial install. This is a fork of the install script by @jacknagel that works around some permission issues. https://gist.github.com/1140207
Don't forget to install the requirements (Xcode, X11, Java Developer Update) mentioned in the installation guide.
python and stuff
brew install python /usr/local/share/python/easy_install pip /usr/local/share/python/pip install --upgrade distribute
homebrew sets things up so that all packages installed via
python setup.py install,
pip get their commands installed to
/usr/local/share/python/ by default (see the above link for an explanation). So the first rule of business is to add that path to your
PATH. Also if you want to use your homebrew python (and other homebrew stuff) by default,
/usr/local/bin should be all the way at the front of your
PATH=/usr/local/bin:/usr/local/share/python:$PATH export PATH
remember to open a new terminal or call
source ~/.bash_profile in all of your open terminal windows to get
Before installing stuff with pip, make sure the above
PATH changes worked and you are using the correct version.:
should return something like (a path with
pip 1.0.2 from /usr/local/lib/python2.7/site-packages/pip-1.0.2-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 globally then.
If you need FREETYPE, choose one of these three options. I recommend Pillow:
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
PIL with patching setup.py
Since PIL is not packaged correctly, setup.py needs to be tweaked.
Use the newest version of PIL from http://www.pythonware.com/products/pil/ and edit
FREETYPE_ROOT = ("/usr/x11/lib","/usr/x11/include",) in setup.py. Then:
python setup.py build_ext -i python setup.py install
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://firstname.lastname@example.org/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 :-)

Other useful tools
git and hg:
brew install wget brew install git brew install hub brew install git-flow brew install gist brew install git-extras git-hg git-multipush git-sh git-svn-abandon git-utils pip install mercurial
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 removed
-arch x86_64 near the end of
setup.py and the ran
python setup.py install and it worked fine.
install and make the command globally available:
brew install gettext brew link gettext
