[Zope] 2.2.1 and zdiscussion

[Bak @ kedai]

hi
a clean install won't start properly  with ZDiscussion product install.  the 
same thing also with ZDiscussion based classes created.

tracebacks when starting

ImportError: cannot import name ZDiscussions 

this is a bit frightening since i have a zclass subclass on zdbase in 
production server  and this prevents me from being on the latest stable 
release.  can anything be done?

this on rh linux, 2.2.1 final 

thanks
