adding MPI support to octopus

[dstrubbe (David Strubbe)]

In this patch to the octopus Portfile, I add support for compiling with openmpi or mpich. (Unfortunately, mpi2 is not usable with openmpi, as reported in ticket #39826.) The Fortran variant of these compilers are checked against that used for libxc, netcdf-fortran, and etsf_io. A similar mechanism is used to make sure fftw-3 was built with Fortran support. gcc48 is also added as a variant.

When I applied the patch and attempted to install octopus, I see the following error:

--->  Fetching distfiles for octopus
Fortran compiler is gcc47.
Error: org.macports.fetch for port octopus returned: Registry error: netcdf-fortran not registered as installed & active.

Indeed, I do not have the netcdf-fortran port installed. I feel this is a bug because it should install it if it is needed and not ask me to manually install it.

Thanks for trying it. I agree, that should not happen. What variants were you installing with?

[mf2k (Frank Schima)]

I used +newuoa +gcc47.

[dstrubbe (David Strubbe)]

Ok I see the problem: I was checking variants for netcdf-fortran even when +netcdf was not selected and so it wasn't a dependency. Can you try this revised Portfile?

That worked. r108659.
