This is a known "problem" with RHEL 6 that burned me, too. I say "problem" in quotes because in my case, it only appeared when I tried to install RPMS built for RHEL 5 on a RHEL 6 system. That's a problem to me, but some purists don't see this is a problem and just say "Well, that's what you get for trying to install RHEL 5 RPMs on a RHEL 6 system. I don't agree with them. As a work around, i think I did some magic with rpm2cpio, as documented above, but I don't remember the details. -- Prentice
