This test is checking whether you have working 64-bit-tzdata support.
It seems you don't.
If you built with --with-system-tzdata, and RHEL4 doesn't include
64-bit tzdata files, then this failure would be expected. (I'm not
totally sure about the second premise, but some quick digging in
the specfile's changelog suggests that Red Hat only started to
support 64-bit tzdata in RHEL5.)
I'm not sure whether to recommend not using --with-system-tzdata.
If you don't then routine platform updates of tzdata won't help
Postgres; that might or might not be worse than not having working
post-2038 DST calculations.
