Using openmpi-1.0.1. attemping to launch programs via 'mpirun --mca
pls_rsh_agent ssh' fails if the user login shell is tcsh, and
LD_LIBRARY_PATH is unset at startup.
if ($?FOO) setenv BAR $FOO
is an error in tcsh if $FOO is unset, because it expands the whole
line at once. Instead one has to use:
if ($?FOO) then
setenv BAR $FOO
endif
Hence the following patch to orte/mca/pls/rsh/pls_rsh_module.c seems
to fix things:
