This should work in svn (r13). You can easily run the development  
version straight from a svn checkout:

svn co http://svn.pythonmac.org/py2app/py2app/trunk py2app
cd py2app
python setup.py develop

That'll set it up such that the "installed" py2app is actually what's  
sitting in your svn checkout. You can make changes without re- 
installing or anything.
