 pgplot is written in Fortran, thus it needs a compiler built for it. The
 current Portfile has a PPC variant with the compiler set to gcc34/g77, and
 a i386 variant with the compiler set to gcc42/gfortran.

 g77 is a little outdated, and requires a gcc 3.x compiler to build. I have
 not been able to get g77 to build on 10.5.x.

 What I have done is to refactor the existing Portfile to remove the
 PPC/i386 dependencies so that pgplot compiles with gcc42/gfortran as a
 default variant, and gcc34/g77 is selectable as a variant for
 compatibility with existing installations.

 I have tested this Portfile on a PPC/10.4.11 system and on a i386 10.4.11
 system. The existing patch files are unchanged.

 What is the process to put this refactored Portfile in the Macports
 repository?
