[Zope] Problem installing zope products

[Darrin Nova]

Hello,

I am having problems installing zope products (*.zexp files) using the import 
function.

I have tried several products including TimeTracker-0.0.3.zexp, 
EvTracker.zexp, ZPhotoAlbum-1.0.zexp and others. I get the same error when 
trying to install these three.

For example with Time Tracker I get...

The object TimeTracker does not support this operation
   
Traceback (innermost last):

I am running zope 2.2.4 on Debian Linux (Potato). I installed this from source 
instead of from the .deb in the /opt/zope/Zope-2.2.4-src/ directory as you can 
see from the error mesages.

I can't understand why these errors occur. The scripts under zope are all 
owned by the user nobody.

Some help or guidance would be greatly appreciated since these products seem 
quite powerfull and usefull.

Thanks.
