Umm, why are you trying to upgrade glibc?
Hint - do NOT compile it from the source, do NOT download random RPMs of it from the net. The only time you should *ever* upgrade glibc is when your distro puts out security updates for it on their updates service.
glibc is a core system component, if you play with it without understanding your system very well, you *will* break your installation completely.
As for installing packages, we're working on it.... not an easy problem to solve unfortunately
