This had not been a problem elsewhere, but I can see why it does not work with py2app.  So, I'll make sure to avoid a name collision between my init module and all packages, which sounds like a good practice to follow anyway.

   My script works as 'python quot.py' and now I am trying to bundle it 
up for my users to be able to click and run.  So, yes, from Terminal, 
AppKit imports correctly and the AppKit.NSSound module works well.

   Looking at the various logs reported by py2app, it does not appear 
that the needed dirs are added to the app bundle's sys.path.  The follow 
process creates a failing AppKit import from the app bundle for me and 
shows different sys.path for 'python quot.py' vs app bundle launch.  I 
can provide much more detail (including modulegraph debug output) if 
requested, but the following steps in a Terminal window can reproduce 
the error for me every time.

$ echo "import sys" >> quot.py
$ echo "print sys.path" >> quot.py
$ echo "import AppKit" >> quot.py
$ cat quot.py
import sys
print sys.path
import AppKit

$ py2applet --make-setup quot.py
Wrote setup.py

$ python quot.py
NOTE: list of dirs in path

$ rm -rf build dist && python setup.py py2app
running py2app

$ open -a quot
NOTE: Error window appears and output is captured in Console which can 
be condensed to "ImportError: No module named AppKit".


   I believe I can overcome this error by finding the right path(s) to 
append to the app bundle's sys.path, but I'm surprised that py2app does 
not do this automagically.
