I'd assume that your undefined references were added in later versions of
glibc. Remember that Fedora 13, for example, has more recent libraries, in
some cases, with enhancements to the ones in CentOS. CentOS 5/RHEL 5 are
based on FC 6 or so. With these, you get stability, but not the newest
releases of some libraries.
