Kent answered your questions well enough.  However, I suspect question 
"c" may result from a misunderstanding of MPI_EXTRA_LIBRARY.  This does 
not mean an entire extra MPI implementation.  Like Kent says, just pick 
one, either LAM or OpenMPI.  Use the full path of the main library file 
(e.g., libmpi.so) for MPI_LIBRARY.  If your chosen MPI implementation 
has other libraries that require inclusion, then add those to 
MPI_EXTRA_LIBRARY.
