The RPM's that I have don't cover all of the modules. You should be able uninstall what your system thinks are the horde, imp, turba, ingo (default SME), kronolith, nag, mnemo, gollem (From me), then mount your CD and re-install horde, imp, turba, ingo, smeserver-horde, imp, turba, ingo, then signal-event post-upgrade ; signal-event reboot and possibly fix your system.
