It has nothing to do with the version number. Read the log file you included in your original post. You'll find /home/dcs/dcs/usr_local/lib/libmpfr.so: undefined reference to `__gmpz_tdiv_q_2exp' /home/dcs/dcs/usr_local/lib/libmpfr.so: undefined reference to `__gmpz_fdiv_q_2exp' /home/dcs/dcs/usr_local/lib/libmpfr.so: undefined reference to `__gmpz_clear' /home/dcs/dcs/usr_local/lib/libmpfr.so: undefined reference to so the mpfr test never compiled and configure assumes the mpfr test fails. It of course makes a difference. mpfr must be linked with the version of libgmp that was used when mpfr was built. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40833
