Where did you put that 'export'? Hydra/mpiexec establishes connections 
to all the nodes itself so any changes you do to the environment of an 
interactive ssh session will not apply.

Try putting that 'LD_LIBRARY_PATH' line into '.profile' on each of the 
compute nodes so it gets executed for every session. Or just make sure 
that the directory structure is the same on all nodes as Kenneth suggested.
