gmp w/ mpfr for gcc's f95

[Hugh Sasse]

All the tests passed, so I installed the library.  My config.log
from the gcc build ends up with 

configure:2284: checking for MPFR
configure:2297: gcc -o conftest -g -O2 -I/usr/local/include -I/usr/local/include   conftest.c  -L/usr/local/lib -L/usr/local/lib -lmpfr -lgmp 1>&5

int main() {
mpfr_t n; mpfr_init(n);
; return 0; }


I don't mind that it skips the ones in /usr/local/lib/gcc, but the
ones it finds first are the new ones, which it claims are not
compatble.  What should I be looking at now, please?

        Thank you,
        Hugh
