emerge sys-cluster/openmpi-2.0.2[fortran] lacks at least to install /usr/include/mpif.h
I cannot build sci-libs/hdf5 with it.
I know Fortran is short for formula translator, it's old and there are 2 or 3 main releases, that's it.
Well except for a more very very special file - I don't remember the name, but it was much longer than just mpi.fh or mpif.h i couldn't find any fortran includes, that hdf5 complaint about while doing configure, so
I installed sys-cluster/mpich2 as ALTERNATIVE to get virtual/mpi and built hdf5 with that, which worked an gave me /usr/include/mpif.h among others.
Sorry, I can not give you more Information, as I would have to break my system to make more investigation.
Reproducible: Didn't try
Steps to Reproduce:
crucial fortran headers for mpi missing,
I have not checked the libs.
basic fortan mpi support
4.0.5-r1 installs it properly
