The environment will be different when started by a queuing system, at least for SGE I know this for sure and I think also for Torque/PBS. To investigate, can you please submit a job with:

#!/bin/sh
echo $LD_LIBRARY_PATH
ldd /path/to/your/application

If we know this, we have to check the processes on the slave nodes of the parallel job. Usually they are not started by an `ssh`, but some builtin mechanism inside the queuingsystem. So, submitting a job with this should show it:

#!/bin/sh
mpiexec echo \$LD_LIBRARY_PATH

It's necessary to escape the $, as we want to get the result from the slave, not where the jobscript is executed.
