Comment (by dstrubbe@…):

 Ha, funny that Sean was looking at this at the same time. Unfortunately
 given how our "Tickets filed against a specific port" search works with a
 regex, trying to search for "R" is pretty hopeless.

 I don't think a revbump is needed, since what was already installed
 shouldn't change (except conceivably regarding the configure.args comment,
 if the trailing args are important).

 Why is there a need for matching the GCC version used in some other
 binary? I don't see any mention of GCC versions at
 https://cran.r-project.org/bin/macosx. Anyway, gcc5 is the default Fortran
 compiler across MacPorts; it is helpful for ports to use the default
 unless there is a good reason otherwise, to minimize the need for users to
 install multiple versions of GCC.
