I have upgraded from Zope 2.8.5 to 2.9.4. This currently works in the
2.8.5 instance but not in the 2.9.4.
I have a Module Progress in /usr/lib/python2.4/site-packages/Progress
containing 4 files:
__init__.py __init__.pyc Progress.py Progress.pyc
Both instances have calls to neuro.py which includes:
from Progress import Progress
The External Method in both instances looks good. I even updated the
External Method by clicking the Save Changes button without
error in the new 294 instance.
But when I access it from the dtml-method it goes boom:

But Progress is in: /usr/lib/python2.4/site-packages/Progress !
If I just start python at the command line I can import Progress w/o
error. I'm guessing that it has something to do with how
cPickle is sandboxed by Zope, but I just don't get it.
It does not look like a Zope (version) issue:
The import in an External Method is a pure Python import -- without
any restrictions or additional magic.
Therefore, if sys.path is still correct inside the External Method,
all modules/packages reachable by sys.path should be importable.
I would check sys.path.

[Zope] External Method cPickle Import Module Error

I don't see any indication for a cPickle issue. *Trible* check that your
Zope instance use the system Python installationl. Check your file
permissions, check sys.path, check your $PYTHONPATH.
