$ /usr/local/share/python/pip install --upgrade distribute

Add to .bashrc:

# Before other PATHs...
PATH=${PATH}:/usr/local/share/python

# Python
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python2.7
export VIRTUALENVWRAPPER_VIRTUALENV_ARGS='--no-site-packages'
export PIP_VIRTUALENV_BASE=$WORKON_HOME
export PIP_RESPECT_VIRTUALENV=true
if [[ -r /usr/local/share/python/virtualenvwrapper.sh ]]; then
    source /usr/local/share/python/virtualenvwrapper.sh
else
    echo "WARNING: Can't find virtualenvwrapper.sh"

I had to add the --universal for the install the sqlite and gdbm because when I tried to install python it showed this error:

Error: python dependency sqlite not installed with:
    --universal

I get a:

From the .bashrc

I had to change from:

    if [[ -r /usr/local/share/python/virtualenvwrapper.sh ]]; then
        source /usr/local/share/python/virtualenvwrapper.sh

to

    if [[ -r /usr/local/bin/virtualenvwrapper.sh ]]; then
        source /usr/local/bin/virtualenvwrapper.sh

to make it work, because virtualenvwrapper.sh got installed there.

Thanks for this.

Just wanted to point out that I had to do this

brew install readline sqlite gdbm --universal

to get it to work

$ brew install python --universal --framework

Homebrew already does dependency resolution - no need for this line!

A lot has changed in homebrew and these instructions are out of date. brew install --universal should take care of most of your problems. Also take a look at brew info python for installation instructions.

export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python2.7
if [[ -r /usr/local/bin/virtualenvwrapper.sh ]]; then
    source /usr/local/bin/virtualenvwrapper.sh
else
    echo "WARNING: Can't find virtualenvwrapper.sh"
fi

Also seems to be more recent...

After install python, I find easy_install, virtualenvwrapper.sh and so on in /usr/local/bin not in /usr/local/share/python. just like bdejong shows above.
