#39365: arpack @3.1.1 +openmpi or +mpich configure fails if mpi wasn't built with
fortran wrappers
------------------------+--------------------------------
 Reporter:  dstrubbe@…  |      Owner:  macports-tickets@…
     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.1.3
 Keywords:  haspatch    |       Port:  arpack
------------------------+--------------------------------
 The variants +openmpi or +mpich make the build fail if openmpi/mpich were
 not built with Fortran support, since configure cannot find (open)mpif77.
 We should use active_variants to make sure the dependency was built with
 Fortran support, and indeed it probably needs to be the same Fortran
 compiler as is being used for F77.

 A more minor issue: building with MPI causes some PARPACK test programs to
 be installed.

 {{{
 Port arpack contains:
   /opt/local/bin/pcndrv1
   /opt/local/bin/pdndrv1
   /opt/local/bin/pdndrv3
   /opt/local/bin/pdsdrv1
   /opt/local/bin/psndrv3
   /opt/local/bin/pssdrv1
   /opt/local/bin/pzndrv1
   ...
 }}}

 By analogy to the ARPACK test program {{{dnsimp}}}, these should probably
 not be installed. They don't work anyway, for me at least, even though
 PARPACK works fine in an application.

 {{{
 $ pcndrv1

 dyld: Symbol not found: _second_
   Referenced from: /opt/local/lib/libparpack.2.dylib
   Expected in: flat namespace

 Trace/BPT trap: 5
 }}}

 Attached Portfile diff establishes active variants requirements and
 removes test programs from installation.

 Also, it seems from livecheck that arpack 3.1.3 has been released, so I
 guess that could be updated in the port.
