Ouch!
Did you distro not come with sound libraries, that you could install without trashing your system.
Once you have your system stable and managed to unpack the RPMs, just remember to add the exports for CRYSTAL, CEL and CSCONFIG variables in your .profile, .bashrc or .bash_profile which ever one exists. Then add write access for your account (normal user) account to all files/directories in the CS, planshift or CEL directories.
Then you be with me stuck with the updater.
