MPFR error

[Jenn-Ching Luo]

GMP (4.2) and MPFR (2.2.0) were built without error. However, when trying to
build gfortran, I got the following. What may be the cause? Thank you.





       undefined reference to `___gmpfr_default_fp_bit_precision@INDNTPOFF'

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