What's more likely? That I said earlier that the point of the modules you
loaded is that you are using the magic wrapper compilers Cray provides to
handle MPI for you, or that I'm wrong about that *and* about my assertion
that MPI_LIBRARY was useless? :-)

Not needing to know about such garbage is why you should be asking your
system administators to do these infrastructure things for you...
