I don't think I can upgrade the libc on this machine.

I've just tried it on a very differently configured machine (perl -V output for that one is below) and it doesn't seem to have the same problem, unfortunately the above configuration is what we use everywhere.
perl -V that works fine (this is the default perl for RedHat enterprise 3.0):
