Thanks. Apparently the mpfr.h header file is in /usr/local/include. How do I point gcc to this location? I've tried each of the following flags on the configure command: --with-mpfr=/usr/local --with-mpfr=/usr/local/include --with-mpfr=/usr/local/lib --with-mpfr=<path-to-mpfr-source>/mpfr-2.4.1 I get the same error with each of these.
