Incompatibilities between RPM & .tar.gz versions of ghc-6.0.1

Yes, this is entirely possible.  I'm not sure of the exactly list of
things which must be identical in order to get two binary-compatible
builds, but I suspect that having exactly the same OS / platform is a
good start (the RPM and binary tars were built on different versions of
RedHat Linux).
