It looks like you have LAM/MPI 7.0.0 installed as the default on one
node, and 7.1.1 as the default on another.
You might want to check differences in your PATH between interactive
and non-interactive logins (i.e., you want to make sure that you're
getting the same version of LAM -- assumedly 7.1.1 -- for both
interactive and non-interactive logins). See the FAQ under the
"Booting LAM" section for more details about shell startup files, etc.
