[Pythonmac-SIG] [py2app] No module named os

[Chris Weisiger]

Whelp, this problem is back, with a different program this time. All the
fixes I have written down from last time don't work. Fortunately this time I
don't have any dependencies on weird homegrown libraries that require hours
of fiddling -- just on wx, paramiko, and Crypto.

To recap: py2app generates an application successfully. Per my post earlier
today (
http://old.nabble.com/py2app-program-unable-to-find-files-in-lib-dynload-td29679814.html),
I then hack __boot__.py to modify sys.path so it can find SHA256.so.
The
program runs just fine on my development computer. I take it over to a
client computer and try to run it. It tries 'import os' and fails.

Last time I speculated that this was due to stale pyc files hanging around.
I've removed all pyc files from the app and it still fails, so that's not
what's going wrong here. Without access to os, I can't check environment
variables, let alone change them. Frankly I don't have a clue how to debug
this short of random flailings -- and I spent three days or so on that last
time before stumbling across something that worked. Comparing that working
program to this nonworking program hasn't turned up any obvious
discrepancies, though.

Anyway, my source code is online here:

If you have any insight into this problem, I'd love to hear it.
