Early versions of mpfr didn't build shared libraries by default. Such old versions would no longer be useful. Configure has a minimum version requirement for recognition of mpfr. If your mpfr is actually installed, e.g. in /usr/local/lib, do you need to specify more of the path to configure? My preference is to replace entirely the mpfr in /usr/lib, so there isn't any problem with picking up wrong versions, or need for --with-mpfr. I don't believe there is a satisfactory version of gfortran which builds without mpfr. For the other compilers, I suppose dropping back to 4.3 may avoid use of mpfr. I may try updating my IA64 gcc today; I haven't done it recently enough.
