Great idea to examine EGG-INFO/SOURCES.txt, Jim! I just added this to  
my recipe (http://pypi.python.org/pypi/rod.recipe.appengine) and got  
rid of the horrible monkey patch for imp.load_dynamic. Now it does  
exactly what Tim wants and excludes the optional c extension stuff  
(plus .pyo, and .pyc files) in a gae buildout. I'm planning to add an  
option for not deploying the additional packes as a zip archive if the  
gae file limit will not be exceeded.

Cheers,
Tobias
