[Zope] Incompatibilities

I've been bracing myself for this to happen because of the large potential for conflict among different versions of Python, Zope, CMF and Plone... I got as far as adding Plone without problems but I can't get Plone to work at all and my gut feeling is that there is some version incompatibility since I get:- Zope Error Zope has encountered an error while publishing this resource. Error Type: AttributeError Error Value: get when attempting to add my first Plone site. I'm using:- Python 2.2.2 Zope 2.6.2b3 CMF 1.4.2 Plone 1.0.5 Is this combination known to work? -- John
