[Pythonmac-SIG] Py2App and adding paths to sys.path

[Christopher Barker]

Hi all,

I'm trying to bundle up a pretty complicated app.

During the app's initialization, a path is added to sys.path, so that it 
can see the app's  "library" code:

app_root = os.path.dirname(os.path.dirname(os.path.abspath(
         os.path.realpath(__file__))))
app_lib_dir = os.path.join(app_root, "lib")
sys.path.insert(0, app_lib_dir)


So it looks to see where the initialization file lives, then it adds the 
"lib" dir relative to that.

This clearly won't work right with py2app.

My solution, so far, is to wrap the above in a "if sys.frozen is not 
None" call, so it doesn't run. Then, I added that path in the top of my 
setup.py, so py2app can find all the modules it needs.

This works mostly OK with the app bundle, but doesn't work when I try to 
run in alias mode, which I'd really like to be able to do.

Also, while it mostly works with the app bundle, I am having some 
trouble with the durus database, which uses pickles -- I think it's 
having trouble finding the modules it needs to unpickle some stuff. I'll 
need to dig into this deeper, but it seems maybe I'm just not doing this 
right.

Suggestions welcome.

-CHB
