Code review comment for lp:~danilo/linaro-license-protection/cleanups

I've tried it on Lucid as well (with Python 2.6), and there are a few problems:
 - more dependencies are needed (will update the README)
 - testtools and testrepository that come with it are too old
 - unittest requires modules to be imported in tests/__init__.py, which is not required with the version coming with Python 2.7.

Since we are not using distribution-provided versions of testtools and testrepository anyway, I'll build the latest versions for Lucid and try it out. If that is not sufficient, I'll claim we require Python 2.7 :)
