Obviously, you'll need these libs on host-1. Even more, they need
to be found in a system library dir (e.g. /usr/lib) or somewhere
inside LD_LIBRARY_PATH. I guess you already know that.

The variable is expanded on the calling host:
adi_at_ipc654:~$ echo $HOSTNAME
ipc654
adi_at_ipc654:~$ mpirun -np 1 -host amun3 echo $HOSTNAME
ipc654
In other words: you're echoing your local LD_LIBRARY_PATH. If this
should be the same on host-1, either set it in your login scripts
(on host-1) or export it with -x:
host-0:~$ mpirun -x LD_LIBRARY_PATH -host host-1 your_prog
