OSX broken pip and virtualenv after brew update

Working on a new project and needed to download some new brew packages that ended up breaking my virtualenv.

This is how I got it back to speed:

xcode-select --install

rm '/usr/local/bin/pip'

# or 
# mv /usr/local/bin/pip /usr/local/bin/pip.old

sudo /usr/bin/easy_install pip

sudo pip install virtualenv --upgrade
