#59799: netcdf-fortran: won't build if mpi doesn't match
----------------------+----------------------------
 Reporter:  dstrubbe  |      Owner:  tenomoto
     Type:  defect    |     Status:  assigned
 Priority:  Normal    |  Milestone:
Component:  ports     |    Version:
 Keywords:  haspatch  |       Port:  netcdf-fortran
----------------------+----------------------------
 The port failed to upgrade, because I had netcdf installed with +mpich,
 but netcdf-fortran was just +gcc7. Apparently we now need to enforce
 compatibility of these variants. I am not sure if this might cause some
 other problem, so I figured I would file a ticket rather than just commit.

 We should enable parallel tests when using MPI, which needed a bit of
 patching to get to work.
