Checking for a C compiler ...... found
Looking for GMP and MPFR libraries ...

******************************************
Couldn't find libgmp and/or libmpfr -
both of which are required for Math::MPFR.

To obtain GMP go to:
http://swox.com/gmp/

To obtain MPFR go to:
http://www.mpfr.org/

If you have these 2 libraries installed,
then apparently one (or both) was not
found. Check the README for instructions.
If the instructions are incorrect, please
notify the author:
sisyphus at cpan dot org

You can, of course, modify Makefile.PL so 
that this test is not conducted - then
re-run it.
