Comment (by iEFdev):

 Thanks… I've added the `makefile 1.0` PG and could remove some code in the
 Portfile.

 While reading the PG: [https://github.com/macports/macports-
 ports/blob/master/_resources/port1.0/group/makefile-1.0.tcl#L139-L149
 makefile-1.0.tcl#L139-L149] Would it benifit to also include the
 `muniversal 1.0` PG as well? …or is the code in the first ''“*not* used”''
 section be suffient enough?
