Comment (by tenomoto):

 I am aware that gfortran10 is stricter and Portfile already incorporated
 the option (-fallow-argument-mismatch is sufficient). You are using mpif90
 -mpich-mp. The current Portfile fails to detect the version of gfortran.
 Checking gfortran and gfortran10 correctly detects the gfortran version
 behind mpif90, but gfortran could be other version and checking for
 gfortran1x variants need to be added in the future. I'll see there is a
 better solution.
