Hi Adrian -
Thanks for the reply. I have been investigating this further. It appears that ssh isn't starting my .zshrc file. This is strange.
If I execute
> ssh host-0 export
I get only a minimal set of environment variables. One of them is SHELL = /bin/zsh. There is no LD_LIBRARY_PATH in the list.
If I ssh into host-0 and type "export", I get my full list of variables.
Seeing as how this is almost certainly an ssh problem, I should probably take this to the openssh mailing list.

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