The problem here is that you (probably) already have zconfig in your
python's site-packages. This is taking precedence over de zconfig
verion that really is required for Grok. The de facto solution for
this is, is to use virtualenv to create an isolated python runtime
(isolated from your system's site-packages that is).

I think there're probably references to this virtualenv solution to be
found in the archives of this list.
