tar zxf virtualenv-1.6.1.tar.gz
python virtualenv-1.6.1/virtualenv.py $HOME/venv
$HOME/venv/bin/pip install virtualenvwrapper

Using virtual environments

To create a new virtual environment, use 'mkvirtualenv', e.g.

 mkvirtualenv buildapi

This will create and activate a new virtual environment where you can install new packages, e.g.

 pip install mysql-python

To switch between virtual environments, use the 'workon' command, e.g.

 workon buildbot-0.7

All of the heavy lifting here is done by virutalenvwrapper
