R build fails due to g95 dependency, despite specifying gcc

[klausness]

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?"

How do you get a dependency on g95? R uses gfortran from gcc13, nothing uses g95.
