Hi Jeff, >From the config.log it appears that you do not have the prerequisite libmpfr.so. Where did you untar MPFR? It's easiest to untar in the GCC source code location, as per the instructions (see below), or to put in a soft-link to the MPFR in the GCC source code directory. If you hadn't untar'd MPFR for the build, you may also have missed untar GMP for the build. http://gcc.gnu.org/install/prerequisites.html Sincerely, --Eljay
