You would want to use --with-gmp-lib=/usr/lib64 or --with-gmp=/usr but the compiler will always look in /usr/lib64 anyway so you shouldn't need to use any --with-xxx options for gmp, mpfr and mpc if they're installed in /usr For more specific information on what fails you will need to look in the config.log file.
