All the packages you have listed are newer than S-C-P expects. This is a known issue with S-C-P.
So, once a system is brought up to date s-c-p no longer works. This seems like a major problem.
Use yum or up2date to install additional packages.
I am a lowly dialup user (rural area), so yum and up2date would take far too long. Is there another way to install the package groups from the CD without hand picking the 52 packages I need installed?
