[Zope] External Method cPickle Import Module Error

[Sean W. Duffy]

Hi,

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:

Traceback (innermost last):
 Module ZPublisher.Publish, line 115, in publish
 Module ZPublisher.mapply, line 88, in mapply
 Module ZPublisher.Publish, line 41, in call_object
 Module Products.ExternalMethod.ExternalMethod, line 134, in manage_edit
 Module Products.ExternalMethod.ExternalMethod, line 141, in getFunction
 Module App.Extensions, line 148, in getObject
  - __traceback_info__: ('/var/lib/hip_294_251/Extensions/neuro.py', 
'neuro')
 Module /var/lib/hip_294_251/Extensions/neuro.py, line 299, in ?
 Module /var/lib/hip_294_251/Extensions/neuro.py, line 9, in GetProgress
ImportError: No module named Progress

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.

Any guidance sincerely appreciated,

Sean
