What could cause this?
What version of python and py2app do you use?
To debug you can add a print statement to
yourapp.app/Contents/Resources/__boot__.py. In particular, add these two lines
to the top of that file:
import sys
print sys.path
If all is well the correct lib-dynload should be on sys.path before the zipfile
containing the rest of the application. One thing you could also try: edit
py2app/build_app.py and look for 'compressed = True', change that to
'compressed = False'. This ensures that the zipfile with the application files
won't be compressed. That's not guaranteed to give a useful result though,
there may be other problems with the application bundle.
