Jennifer,
My understanding is that both gmp and mpfr are prerequisites (must be installed) when installing gcc. The simplest method is to unpack both gmp and mpfr into the unpacked gcc directory. Here's a 'visual':
This assumes gcc, gmp, mpfr tarballs in same directory.
$ cd /path/to/gcc/tarball
$ tar -xjf gcc-<version>.tar.bz2
$ cd gcc*
$ tar -xjf ../gmp*
$ tar -xjf ../mpfr*
$ mv gmp* gmp
$ mv mpfr* mpfr
Then run configure and make commands (per installation instructions) to build gcc.
Hope that helped,
Harvey
