[TransWarp] Re: Problem with TW

[Phillip J. Eby]

I would recommend you add your Zope's lib/python directory to your Python 
path; It sounds as though the version of the Interface package you're using 
isn't up-to-date enough.  Also, although the TW core will work without 
ExtensionClasses, the test suite currently *does* require 
ExtensionClasses.  You also need to be using a Zope 2.4.x release, for 
compatibility with Python 2.1.
