Using buildout has some problems. So we need to write up
instructions in the hacking howto for setting up a
build/development environment using virtualenv --no-site-packages.

Running python setup.py develop on Ubuntu Natty doesn't work. PIL
doesn't get compiled with jpeg or png support. This happens with
both the virtualenv and buildout instructions.

Doing a Google search leads to the following interesting urls:

This is a big deal because it means people using Ubuntu Natty can't
run GNU MediaGoblin.

We're having some issues with getting PIL installed into the
development environment. Chris talked with the deviantart folks and
discovered they're not using PIL--they're using imagemagick.

This issue is for the following:


1. researching the pros/cons of switching
2. checking to see if there are other options
3. if it seems like a good idea and the other options aren't
   enticing, looking at switching GNU MediaGoblin over to using
   imagemagick
4. if 3 happens, then updating all the docs
