Create a virtualenv for the person

Install the virtualenv package
sudo apt-get install python-virtualenv

If that doesn't work, try:

sudo apt-get install python-setuptools easy_install virtualenv

Create a virtualenv
virtualenv ~/env

Activate it
source ~/env/bin/activate

You should now see

(env) at the start of your shell prompt. Look for that!
