Can you explain in plain English what a 'NSF Xsede stampede cluster' is? Is
it Linux based? If so, what distro? What compiler does it use?

There are two things here.
You need to understand first which MPI version you have (typically: Open MPI,
or MPICH) and where it is stored. At this point I recommend a very simple
plain C program (no R) to just include MPI headers and library and get it
work, and run across more than one machine. At this point we have MPI.
Next is to get into to work with Rmpi. In its configure script, a simple
shell script loop runs over a number of candidate locations. Yours are
seemingly not part of this; so you need to adjust this. It is not hard, but
involves a few minutes with a new 'language' (ie autoconf). We can help.
But try to get the first step sorted out first, please.
