Yes, I could, but then the entire package gets included, not just the 
pyc files that I need -- not really a big deal, but it doesn't seem as 
clean as it could be.

I think I've got this figure out. The database itself is created with a 
separate program. This program just reads it. However, it needs to have 
all the modules that were used to create the database in order to 
unpickle the objects in the database. py2app didn't include this module, 
because it's imported on unpickling, and therefor never explicitly on an 
import line.

Solution:
Force the inclusion of the module at hand.

the module I need is:

cameo.model.reactivity

However, I tried that with:

OPTIONS = {...
            'packages': ['cameo.model'],
            ...
            }

but what got put in the package was:

model

so that it would import as:

model.reactivity

so I did:

'packages': ['cameo'],

which did work, but then I got ALL of the cameo package, including both 
.py and .pyc files, plus most of them were included in the site_packages 
zip file anyway.

I'd think there'd be a way to specify a single module to be included in 
the site_packages zip -- WITH the same package structure (in this case, 
cameo.model. was there, with other modules, just not this one.

Anyway, the solution for now is just to put a:

import cameo.model.reactivity

line in one of the main modules of the app, so now py2app is finding it. 
It seems there should be a more elegant way, though.
