note that py2ap will not bundle up python itself in this case, and your 
app will only work on 10.6 systems.

hmmm -- this means it's looking in your system, rather than the bundle, 
for the wx libs...

stripping does not mean removing -- I thin it means removing debug 
symbols, etc, i.e. making it smaller. It should not cause this problem.

Aside from putting dylibs into the bundle, py2app also re-writes the 
headers, so that they are linked against the copies in the bundle, 
rather than the system ones -- it looks like this has gone awry.

Do take a look in the bundle ans see what's there. It's very helpful for 
debugging.


I'm not running 10.6, or python2.6, so I'm not much help here, but do 
make sure that you are running the latest py2app -- there have been 2.6 
fixes recently.

You also might try installing a Python.org build, and using that instead 
of Apple's -- you'll need to do that if you want to support older 
systems anyway.
