[p2pu-dev] Error with PIL Image module

[David Beckley]

Hi,

I was following Lernanta's
Setup/Install<https://github.com/p2pu/lernanta/wiki/Lernanta%27s-Setup-Install>on
the GitHub wiki.

I installed PIL with `sudo apt-get install python-imaging`. Then, the
instructions told me to use `mkvirtualenv lernanta`.

I've done some Python scripting in the past with Blender, but, I've never
used Django before.

Should I continue using my modified version of Lernanta for development? Or
will something explode?

Thanks!
David Beckley
