[Zope] CMF install failure on _checkCBlock

[Barry Russell]

I'm getting "broken" on attempts to install CMF 1.0 from the .zip version onto an 
NT4 system (a previous mailer reported the same problem on Mandrake Linux). 
It seems to occur in CMFCore in FSPythonScript when assigning an attribute 
value to _checkCBlock. Traceback below. Any ideas ?

Thanks,
Barry
