That does help. I confirmed that what I added needs to be in the
environment (LD_LIBRARY_PATH). Must have missed that in the docs. I
have now added the appropriate variables to our modules environment.
Seems strange that OpenMPI built without these being set at all. I could
also compile test codes with the compilers, just not with mpicc and mpif90.
