Checking for a C compiler ...... found Looking for GMP library ... ****************************************** Couldn't find libgmp which is required for Math::GMPf. To obtain GMP go to: http://swox.com/gmp/ If you have this library installed, then apparently it 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. ******************************************
