Comment (by barracuda156):

 Well, the fix is easy, adding `compilers.setup require_fortran` into the
 portfile.

 What I do not understand (and I have noticed this happenning a couple of
 times with some ports) is why only some configurations all of a sudden
 decide to link to `libgfortran` but not others. This port passed CI
 earlier, which means it did not ask for `libgfortran` that time.
