[py-dev] Import errors

Well, I'm doing a big renaming, and the errors from bad imports are a bit confusing. It seems whenever there's an import error, the module with the error still gets loaded, but is empty. This is a bit confusing to debug. Well, this isn't true in the test_* module, but in the modules they import. -- Ian Bicking / ianb@colorstudy.com / http://blog.ianbicking.org
