Update from version 1.19.2nb18 to 2.1.2.

Pkgsrc changes:
o Change to Module::Build
o Change MASTER_SITES to use CPAN
o Change location of packlist
o Add a few local patches to deal with some issues in this version:
  1) Use appropriate include paths for GL headers
  2) Import fix from CPAN bug 19155: ensure modules are installed
      in the correct directory
  3) Add a missing type to the typemap
  4) Import fix from CPAN bug 32744: ensure Module::Build leaves
      a packlist behind (define module_name).

With these changes in place, the module at least passes its own selftests.
