[Pythonmac-SIG] Py2app/modulegraph crashes on pkg_resources

[David Eyk]

My apologies to Chris Barker--I accidentally took this discussion off
the list, too. A common newbie mistake, it appears? His advice fixed
my initial issue, but py2app is still failing mysteriously on me,  now
for different reasons. I've reconstructed the pertinent bits of my
further problem below:

I did.  Here's the console output:

>>>>

 kernel          : ERROR    AUGGH!!!! Run in circles! Scream and shout!
 Traceback (most recent call last):

 Interestingly:

 $ ls /Users/deyk/code/py/spaaace/trunk/dist/bash.app/Contents/Resources/
 PythonApplet.icns       __boot__.py             data/     lib/
            site.pyc
 Spaaace.py              __error__.sh            include/
  site.py*

 No kernel.pyo, and no bash package actually exist inside the app
bundle. I see them in
"build/bdist.macosx-10.3-fat/python2.5-standalone/app/collect/", but
nowhere else. The run-time error is the same when I move the app
somewhere else and run it. It seems to still be importing them out of
the build tree, and pretending they're in the bundle tree. Weird!

The module that it's trying to import, space.py, isn't in the build
tree. This may be the source of my trouble, as the build-time error
was complaining about the bash package which contains space.py, so
I'll look into it. Still, everything runs and imports trouble-free in
the development environment. Weird!

I tried attaching py2app's console output, but it was too big for the
mailing list. If you're interested in perusing it, you'll find it at

I believe so. I have 1.2 installed.

Nope. Consistently fails.

Thanks for your help in puzzling this out.
