[Zope] The Ghost of PTKDemo

[Ben Ocean]

Hi;
I'm *still* having problems ridding myself of a product that somehow has 
etched its memory into Data.fs. The error I run into states Zope can't 
import module PTKDemo. I moved out all products that weren't essential, 
deleted them out of the ZMI and restarted Zope, but the error remained. 
Here's a traceback:

Any ideas?
