Comment(by russell.jones@…):

 Replying to [comment:2 ryandesign@…]:
 > You also changed the description of the g95 variant from "build with
 g95" to "build with gfortran from f95". There are two problems with this:
 1) the port is called g95, not f95; 2) the g95 port provides a program
 called g95, not gfortran (only gcc provides gfortran). So the previous
 variant description was correct, and should not have been changed.

 Thanks for sorting out my Portfile n00bishness. I'll take more care to get
 it right on my next submission.
