We've been discussing this off-list already. Issues:

- CMake ships a FindMPI.cmake that does rubbish with mpi-ch vs. openmpi (libm.so is _not_ libmpi.so).
- Fortran MPI is a requirement and the f90 option in openmpi is not default.
- MPI libraries in pkgsrc are ancient, outdated. We need someone who actually uses them, ideally, to update and test.

I provide MPI with the compiler toolchain on my HPC systems. So  the neglected state of  MPI packages went past me.

The config that should work is

- MPI_TYPE=openmpi
- PKG_OPTIONS.openmpi=f90

There's fixup needed ... uncovered by my attempt with scalapack.


Alrighty then,

Thomas
