This is an MPICH error message.
You are somehow mixing your LAM and MPICH implementations -- I
suspect that it's the opposite of what I guessed before: you're
compiling against MPICH and using LAM to launch. I don't know where /
etc/alternatives/mpiCC is coming from, but it seems to be compiling/
linking you against MPICH, not LAM.
