This is how I setup virtualenv using pip on Mac OS X 10.6.8 with Python 2.6 (modified from Jontourage).
Install virtualenv and virtualenvwrapper:
sudo pip install virtualenv sudo pip install virtualenvwrapper
Add to .bash_profile:
# virtualenv export WORKON_HOME=$HOME/.virtualenvs source /usr/local/bin/virtualenvwrapper.sh
For the changes to .bash_profile to take effect, open a new terminal window or:
source ~/.bash_profile
