[Zope] LoginManager

[D. Rick Anderson]

I'm not sure that this is the right mail forum, but is anybody using 
LoginManager? We're trying to change from GUF to LoginManager and I'm 
having some problems with it. I spent forever just trying to get 
ZPatterns to work right, but that seems like it's installed ok now. 
Here's what I'm using:

Zope 2.4.3 on RH 7.1
ZPatterns 0.4.3b1
LoginManager 0.8.6 and/or 0.8.8b1 (they both do the same thing)

LoginManager just shows up in the Product Management as a Broken Product 
and this is what it gives for traceback:

Traceback (most recent call last):

  File "/usr/local/Zope/lib/python/OFS/Application.py", line 563, in import_product
    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/ZPatterns/Expressions.py", line 38, in ?
    from DocumentTemplate.DT_Util import Eval, expr_globals, TemplateDict, \
ImportError: cannot import name expr_globals

Both versions that I've tried do this. I've checked permissions and 
tried re-compiling ZPatterns, but it always shows up like this. Any ideas?

TIA
