I have not yet been able to make a working stand-alone app bundle using
py2app and I hope someone can point out what I'm missing. I am using py2app
cloned from bitbucket (changeset 169:9d95dbc52431), but py2app 0.6.3 did not
work, either. This is being done on OSX 10.6.8 with the Apple-provided python
(v2.6.1).
The app (quotidian) is a Tkinter python script that runs well from Terminal
and partially from a py2app --alias app bundle. But the primary problem is
that sub-modules with the project are not importing (see the stderr log below)
on launch. The supposedly missing module is in site-packages.zip (as
queue.pyc). I have verified that site-packages.zip is in sys.path.
Does anyone have something else I can check?
Can you reproduce this problem in a simple standalone application (using
Tkinter is fine)?

Attached is a minimal project (4 lines of Python in 3 files) that replicates
the error I am seeing.
Does your real project have the same structure? The test projects almost
certainly fails because of implementation details in CPython. Your project has
a module and a package named quot that are located in the same directory, which
one gets loaded by CPython depends on the order they are seen by os.listdir.
This happens to work fine on OSX because OSX sorts directories and therefore
the package is found before the module.
It doesn't work when the application is bundled by py2app because the module happens to
be earlier in the zipfile directory than the package, and the import
quot.queue in the main script fails because the import statement only looks at the
quot module which doesn't have a submodule named queue.
That said, the current behavior of py2app is still fishy at best. The 'quot.py'
file is currently copied into quot.app/Contents/ (where is should be located
for the bootstrap code) as well as the site-packages.zip file (and another
location). The copy in the zipfile is not needed, and py2app shouldn't have
copied it into that file.
A quick workaround is to rename 'quot.py' to 'quot_script.py'.
Yes, my actual project had the same structure with a module and
package with the same name. 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.
Thank you for your help. My bundled app is running. Now to find why
AppKit isn't importing...
