Hum, that's more than probably it: FC6 has a GMP which contained an older version of MPFR. The "Prerequisites for GCC" webpage (http://gcc.gnu.org/install/prerequisites.html) says: "MPFR Library version 2.2.1 (or later). Necessary to build GCC. It can be downloaded from http://www.mpfr.org/. The version of MPFR that is bundled with GMP 4.1.x contains numerous bugs." I strongly suggest that you compile a newer MPFR, like 2.2.1. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31971
