I'm afraid that I don't know -- the deb maintainer is an independent
3rd party.

There's two ways to run an MPI application:
1. The application must be available via the PATH (to include .) on all
nodes.
2. You can have LAM push the binary to all nodes and then execute that.
Both work quite well, but note that #2 uses a linear algorithm with UDP
to push the executable out to the nodes, so it may not scale too well.
Check out the LAM FAQ, in particular the section entitled "Running
LAM/MPI applications".
Hope that helps.
