ah, after some extra searching in that general area I found a wiki page that is helpful:
Franklin README - Zimbra :: Wiki -- this provides the guidance I was looking for, p4/Perforce information and pointers towards how to get to the repository. The settings and Getting the source there are exactly what I was seeking. Thanks indeed for the push in the right direction.
OK, do you know of others + forum topics who might have gotten ZCS to compile should I move to/Upgrade to Fedora 9?
