This is unfortunately not much of a LAM problem -- more of a shell/linker
problem.
A few suggestions:
1. Make libgm appear in the same place on all nodes. Here at IU, for
example, a user's home directory is always /u/<username>, regardless of
the unix flavor and/or what server their home directory is actually
mounted on. Hence, $HOME is the same everywhere. It's the same idea.
2. Use static linking. ;-)
3. If you end up using LD_LIBRARY_PATH to specify the location, lamboot
*after* you set it, and then the lamd's will have it in their environment
and you won't need to "-x LD_LIBRARY_PATH" in every mpirun.
