rpl_run.sh sets LD_LIBRARY_PATH, but in doing so, clears out any old content of LD_LIBRARY_PATH, causing issues with profiling applications that depend on LD_LIBRARY_PATH. This pull requests fixes that by instead of overwriting LD_LIBRARY_PATH with new values, prepending the new values to any existing LD_LIBRARY_PATH.
