It looks like you failed to link in the MPI library. I can't really
tell why from your output - I'd need to see the compile / link command
to give you more information than that. LAM/MPI 7.0.x requires, at a
minimum, -lmpi -llam. There are sometimes other flags / libraries,
depending on the platform. You can use mpicc -showme to see what
libraries LAM thinks need to be linked in.
