The operating system is too old. RHEL 4 uses glibc 2.3 and is obsolete and no longer supported. The current release of RHEL 5 is 5.7, which uses glibc 2.5. The current release of RHEL 6 is 6.2, which uses glibc 2.12.

You could search for an updated RPM or download it from GNU's site & compile/install it - but it likely has a ton of dependancies you would also need to update. Might be simpler just to migrate to a newer version of RHEL.
