[Zope] CMFOptions with CMF 1.3?

[abg@comco-inc.com]

Has anyone gotten CMFOptions 1.2 running on CMF 1.3? Mine's throwing the
following error:

Traceback (most recent call last):
  File "C:\PROGRA~1\Zope\lib\python\OFS\Application.py", line 531, in
import_product
    product=__import__(pname, global_dict, global_dict, silly)
  File "C:\PROGRA~1\Zope\lib\python\Products\CMFOptions\__init__.py", line
88, in ?
    import CMFExtImage,CMFExtFile,Blark
  File "C:\PROGRA~1\Zope\lib\python\Products\CMFOptions\Blark.py", line 29,
in ?
    from Products.CMFCore.utils import modifyPermissionMappings
ImportError: cannot import name modifyPermissionMappings

Here's my config info:

Zope Version: (Zope 2.5.1 (binary release, python 2.1, win32-x86), python
2.1.3, win32) 
Python Version: 2.1.3
System Platform: win32

Thanks,
