Perl, the GMP library, and the Math::BigInt::GMP module

[pjacklam at online dot no (Peter J. Acklam)]

I have installed the latest versions of Perl and the GMP library,
and want to install the Math::BigInt::GMP Perl module which makes
use of this GMP library, but I can't make them play together.

There is a complaint "No library found for -lgmp", but I know the
library is installed.  I can also see the files:

   $ find /usr/lib /usr/local/lib -type f | grep -i gmp
   /usr/lib/libgmp.dll.a
   /usr/lib/libgmp.la
   /usr/lib/w32api/libigmpagnt.a

Below are the results from my attempt.  What am I doing wrong?
What must I do to get it working?
