 I think due to this:
 {{{
 IF("${CMAKE_Fortran_COMPILER_ID}" MATCHES "GNU")
   IF(CMAKE_CXX_COMPILER_VERSION VERSION_GREATER 9.9)
     SET(CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} -fallow-argument-
 mismatch")
 }}}
 I.e. they check for GCC version via CXX compiler, but Macports uses Clang,
 so the comparison cannot work as intended.
