Hi Paul,
the configure script doesn't know specifically about Opteron and
LAM/MPI, thus it just looks for a "libmpi.a" (or .so) in standard places
(and complains if not found). If you know where the MPI library is and
how it's called, just edit the make.sys file generated by configure and
add it by hand to LIBS. Then please let us know, so that we can add that
information to the script.
