py2app can't find boot_app.py

[Bob Swerdlow]

I'm trying to move my application from bundlebuilder to py2app.  I upgraded 
to PyObjC 1.2, which include py2app 1.7, but I got the following error.  I 
saw a note on the py2app site that earlier versions need to be removed 
before the upgrade, so I deleted the py2app directory and downloaded and 
installed it separately, but got the same result.  How do I get it to find 
this boot_app.py file?

Thanks,
Bob

Excerpts from the py2app run:

% python setup.py py2app
running py2app
