You may want to read the LAM documentation and/or FAQ; it details the
prerequisites for lamboot to succeed. :-)
You now have a PATH problem -- the LAM command "hboot" is not being
found on the remote node. You need to ensure that your PATH is set
properly in your shell startup files so that the LAM executables can be
found on every node that you're trying to lamboot.
Check out the LAM/MPI User Guide and/or the FAQ under the section
"Booting LAM" for more details.
