[CentOS] Update

I found reason, why update wont go. I have installed much newer
glibc, than what comes with 5.3. I needed that, because of couple
radioamateur progs.
Now have to think, how do I downgrade glibc. If I try remove, there's
over 600 pagages, which have to remove and that's not good.

Hmm...
