        LD_LIBRARY_PATH and LD_RUN_PATH serve different purposes.

        LD_LIBRARY_PATH is read from the env at run-time by all linked
objects (programs), but not by setuid objects. LD_RUN_PATH is a linker
directive that tells the linker to hard code the run time search path
in the linked object. Sun's and GNU's ld will honor LD_RUN_PATH, but
as far command line swiches go, Sun's ld uses -R<path> and GNU's ld
uses '-rpath'.
