#71068: R build fails due to g95 dependency, despite specifying gcc
-----------------------+--------------------
 Reporter:  klausness  |      Owner:  (none)
     Type:  defect     |     Status:  new
 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.10.2
 Keywords:  R g95      |       Port:  R
-----------------------+--------------------
 R appears to have a dependency on g95, even though that cannot be built.

 This appears to be a recent issue.  I had R successfully installed
 already, and when I tried to upgrade it, macports fetched the g95
 distfiles and then gave me a message saying, "building g95 is not
 supported with Xcode 9 or greater".  The R variant I had installed was R
 @4.4.1_2+aqua+builtin_lapack+cairo+gcc13+openmp+tcltk+x11, which
 presumably should not depend on g95.

 When I tried to uninstall R and then reinstall it with just the +gcc13
 variant, I received the message, "g95 is known to fail. Try to install
 anyway?"
