I can't use PlugIns because Zope complains me with:
2001-10-17T09:32:40 PROBLEM(100) Init Ambiguous name for method of
Products.PlugIns.PlugIns.PlugInGroup: "manage_workspace" !=
"manage_main"

Zope version: Zope-2.4.1-linux2-x86
Python version: Python-2.2a4
PlugIns version: ZPatterns-0-4-3p2.tgz

How I can solve this problem?
