That looks odd to me -- as far as I can see (did I miss something?) the
only difference is ABI 102 vs ABI 1002 -- that almost looks like a typo.
I would ask on the wxPython list -- perhaps Robin will recognize those
ABI numbers. And I"m not sure how to get those numbers at either run
time or otherwise -- anyone know?
Meanwhile a couple questions/thoughts:

Unfortunately, at this stage, I do not know what the OS X version is on
the target system.
The app was built using Python 2.5.4, (wxPython 2.8.11.0 or 2.8.4.2 ??)
on OS X 10.6.6.
Is that the "apple's" python? i.e. the one in:
/System/Library/Frameworks/Python.framework/Versions/2.5
If so, that is likely your problem. py2app does not bundle up everything
if you're using Apple's python, so your python install and your users
may be different.
Is there anyway to fix this with a py2app setting ??
not until we figure out what's wrong...
Doesn't py2app copy all the libraries to the app bundle ??
it should, but it won't if you are using Apple's python, and sometimes
things go wrong. wxPython puts itself in /usr/local/, while putting
nifty sys.path manipulations in the python installs, so things can get a
bit confused. But it's done so that one installer can support both
python,org and apple pythons.

no, it doesn't, but it should load on any version that your supporting
libs are built for -- the standard wxPython installers are built for
10.4 and above (maybe 10.3.9 --not sure about that), and so is the
python,org python -- are you using any other third-party libs that
aren't pure python?
debugging suggestions:
-- use the python.org python if you are not already.
-- add a "print sys.path" in your app (before importing wx) -- then
check the console to see what it prints, both in and out of an .app
bundle - that should give you a clue -- if you can have your user report
what they get -- that will be best.
-- take a look in the generated app bundle -- it's just a directory --
you can see what's in there, and it will give you a clue.
What about path settings ??
py2app should take care of that, but looking at sys.path will let you
know if it's doing it "right"
