[Zope-PTK] Can't import DemoPortal.zexp

[Jonathan]

Didn't get any response, so here we go again. I still can't get the 
PTK to work. Downloaded a fresh binary Zope 2.1.6, got the PTK 
straight from CVS and tried importing 'DemoPortal.zexp' from the 
'import' directory after copying everything inside 'ZopePTK' to the 
Products directory.

No dice. LoginManager, Membership and PTKDemo are broken. 
LoginManager gives an error which seems to be related to ZPatterns:

Traceback (innermost last):
   File "/usr/local/zope/lib/python/OFS/Application.py", line 387, in
     import_products product=__import__(pname, global_dict, global_dict, silly)
   File "/usr/local/zope/lib/python/Products/LoginManager/__init__.py", line 1,
     in ? import LoginManager, LoginMethods, UserSources
   File "/usr/local/zope/lib/python/Products/LoginManager/LoginManager.py", line
     7, in ? from Products.ZPatterns.PlugIns import PlugInGroup
ImportError: No module named ZPatterns.PlugIns


Any ideas?
