[p2pu-dev] Error with PIL Image module

[David Beckley]

Hi,

When I installed Lernanta (following the instructions in the GitHub wiki)
and ran `make syncdb`, I got this error message:

    Unhandled exception in thread started by <bound method

    Traceback (most recent call last):

in <module>
        import Image
    ImportError: No module named Image

I updated PIL with the command pip install PIL --upgrade, but the same
error occurred.

Since the line `import Image` was causing the error, I found a list of all
the files containing this with grep:

   - lernanta/apps/drumbeat/storage.py
   - lernanta/apps/projects/tasks.py
   - lernanta/apps/projects/utils.py

Then, I changed `import Image` to `from PIL import Image` in each of these
files. `make syncdb` ran perfectly, as well as `python manage.py runserver`.

I am wondering why these changes were necessary. In case it has to do with
my environment, I am running Python 2.7.1+ on Ubuntu 11.04, following the
instructions on the GitHub wiki.

Everything seems to be working fine... I'm just nervous that it might blow
up sooner or later.
