Comment (by fbissey):
`LD_RUN_PATH` is great with gnu `ld`, I don't know if OS X `ld` takes it
as well. One major problem with `LD_RUN_PATH` is that it is not additive
to any extra `-rpath` option you pass to `ld`. If any `-Wl,-rpath` or
`-rpath` is set, `LD_RUN_PATH` is just discarded.
Case in point: in hashdist Ondrej asked a few months ago if it was
possible to enforce a `rpath`, I provided a patch for `gcc` that change
the spec for linking to add `-Wl-rpath=...`, this is added each time
`gcc`, `g++` or `gfortran` is used linking and `LD_RUN_PATH` will never
be used if you link with that compiler. This is also done by IBM in their
"advance toolchain" for power hardware, no working `LD_RUN_PATH` for you
there either.
