[Answered ]-Virtualenv wont work on

If you are just copying the virtualenv to the second machine you may encounter some issues. From the virtualenv site:

Normally environments are tied to a specific path. That means that you
cannot move an environment around or copy it to another computer. You
can fix up an environment to make it relocatable with the command:

$ virtualenv --relocatable ENV

This will make some of the files
created by setuptools or distribute use relative paths, and will
change all the scripts to use activate_this.py instead of using the
location of the Python interpreter to select the environment.

Note: you must run this after you’ve installed any packages into the
environment. If you make an environment relocatable, then install a
new package, you must run virtualenv –relocatable again.
