[Zope] Zope newbie help with Linux install

I have installed Jeff Rush's rpms (-5 version) for RedHat Linux 6.1. I installed pcgi and made the changes in Apache's access.conf. I always fail authentication when trying to get to the manage screen. I have tried changing permissions in /var/zope to 'nobody' and removing the 'localhost' in the /var/zope/access file. I'm sure I'm missing something simple - anyone have the magic incantation to get this working? Thanks, P.
