Comment 40 for bug 30344

I confirm Tantrik's error message for Ubuntu 7.10. I think that's a missing dependency in gaphor's installation file.
After installing python-setuptools 0.6c6-1 modules /usr/lib/python-packages/pkg_resources.py and /usr/lib/python-packages/pkg_resources.pyc appeared and Tantriks's error message vanished.

Instead of Tantrik's error message I got CyberK's Traceback.

There is a directory component in /usr/lib/python2.4/site-packages/zope .
The directory /usr/lib/python2.5/site-packages/zope is almost empty besides a directory interface provided by package python-zopeinterface for both python2.4 and python2.5

Ali Sabil is right. The zope3 3.3.1-3build2 package provides files for python2.4 but none for python2.5
