Sort of the same problem though.  lamboot (from lam-mpi) assumes
that hboot is in the path.  There's no time before it invokes
hboot to run "modules".  If there were a preceding stage in
this instance just using an export statement with PATH would
have done the trick.

Is there some way to coerce lamboot to either:

1.  set up environmental variables (preferably via  a script) before
running its "hboot" command.
or
2.  run something other than "hboot" (ie /usr/common/bin/hboot).
