- fix build with newer math/gmp in ports tree. Newer versions of gmp do not

define __gmp_const. This patch addresses the compile time errors with an
  ifndef.

while here:
- trim Makefile header
- remove indefinite article from COMMENT
- remove deprecated attribution from pkg-descr and make tab -> space change
  in WWW field
