In that case you'll have to do some manual tweaking to get a working  
application bundle, py2app currently does not support your use case.   
I don't have a handy recipe for it either. The easiest way is  
probably to manually copy the entire /Library/Framework/ 
Python.framework into your bundle and then rewriting the load  
commands in the python executable inside that (in a script using  
macholib [part of py2app]).
