What version of LAM are you using? If it has a "laminfo" command, can
you send the output of that?
Sidenote: you do not need to include <mpio.h> in your application;
including <mpi.h> is all that is necessary.
I suspect that laminfo will show that LAM was not built with ROMIO
support. The easiest thing might be to re-build LAM so that it
includes ROMIO support.
