We are not alone, see:

He does not make any reference to kernels so this may be a generic
problem. Did you try to boot into the RedHat kernel? It would be
interesting for RedHat to know if it is working in the RedHat kernel and
not working on the Planet CCRMA. 

There is a workaround in the bug report for (at least) getting rpm to
work again:

So, for the moment, don't upgrade to the latest glibc from RedHat!!
Again, kudos to Greg for the very fast warning.
