mpirun gives a warning to stderr when trying to report help information:

 mpirun --version
--------------------------------------------------------------------------
Sorry!  You were supposed to get help about:
    version
But I couldn't open the help file:
    /usr/lib/x86_64-linux-gnu/pmix2/share/pmix/help-schizo-ompi.txt: No such file or directory
    /usr/lib/x86_64-linux-gnu/prrte3/share/prte/help-schizo-ompi.txt: No such file or directory.
Sorry!
--------------------------------------------------------------------------

Looks like help files for pmix and prte are missing.

I have also noticed this issue with openmpi's mpirun. Surprisingly it
breaks some 3rd party scripts that try to guess the mpi system from
"mpirun --help". Whether they should or not is a different question.

I asked apt-file, and it told me e.g. help-schizo-ompi.txt (nice name
btw) is in

libprrte-dev: /usr/share/doc/libprrte-dev/help-schizo-ompi.txt

This package is installed, but I suppose mpirun is confused by the
/usr/share/doc location.
