Hmm.  This doesn't appear to have worked, but it's failing in an odd way 
that I don't understand.  Here's what I did:

1. The above copying, vebatim.
2. In the MySQL-python-1.2.2 source directory:
    2a. sudo python setup.py clean
    2b. sudo python setup.py build
    2c. sudo python setup.py install
3. In my project directory:
    3a. rm -rf build/*
    3b. rm -rf dist/*
    3c. python setup.py py2app
4. Ran the resulting app on ANY machine -- even the one I just built it 
on -- and it fails with:

...File "IADB.pyc", line 12, in <module>
  ImportError: No module named MySQLdb

Note that the program still works fine when I run it on the command line 
(with "python eTownCentral.py"), and when I enter python and try "import 
MySQLdb" that works too, so I haven't broken MySQLdb completely.  It's 
just not included in my app bundle now.  Within Frameworks, I see only 
libwx_macud-2.8.0.dylib and Python.framework; no libmysqlclient at all. 
  And in lib-dynload, there is no longer a _mysqldb.so.

The weird thing is, my python source and setup.py have not changed.  So 
why is py2app suddenly failing to realize that it should include MySQLdb?

Thanks,
