It seems to work after I patched pls_rsh_module.c

Another workaround is to add
export OPAL_PREFIX
into $HOME/.bashrc.

Jeff, is this a bug in the code? Or there is a reason that OPAL_PREFIX is not exported for sh/bash?

Yes, this is a bug -- I think your patch is correct.

Sorry about that, but thanks for the patch!
