The current release of py2app doesn't support zipped eggs. AFAIK  
there is no easy solution for converting zipped eggs into unzipped  
eggs. The easiest one is probably to move all zipped eggs to a  
temporary directory and then easy_install them again using  
``easy_install -Z somepackage.egg``.

I have a version of py2app that can extract dependencies from zipped  
archives, but haven't had time to merge that into the repository yet.  
In the longer run I'd like to teach py2app about eggs: it should  
probably include entire eggs instead of just subsets.
