Jonathan, Thank you for your response. I was intending to give back to the open source community by building everything and reporting bugs. Just a small contribution on my part to further the open source concept.

I just built the latest gmp, mpc, mpfr hoping that that was the problem but I still get the msg. It's much simpler just to install them from yum. Running this as root will install the 64-bit and 32-bit devel packages for each: yum install {gmp,mpfr,libmpc}-devel.{x86_64,i686} You might want to uninstall the hand-built packages first, so they don't interfere.
