1) this is off-topic for the gmp-bugs list. Please use the MPFR list instead
   (see http://websympa.loria.fr/wwsympa/arc/mpfr to subscribe)

2) as said by MPFR configure, the found gmp.h corresponds to version 4.3.1,
   but the found libgmp to the older version 4.2.3. You first have to locate
   the libgmp.a/libgmp.so which corresponds to 4.3.1 on your computer, then
   tell configure to use it using LDFLAGS (see the MPFR INSTALL file).

   As also said by the error message, the 'config.log' might contain more
   details. Please send it to us (on the MPFR list).
