As i understand it, the -R... passed to the linker will specify the
rpath (run-time path), while the -L... specifies the compile-time path.
Typically you set -Wl,-L... and -Wl,-R... to point to the same places,
especially in more complex applications in which there may coexist
static and dynamic libraries.

Linux: "Where do you want to be tomorrow?"
NetBSD: "Are you guys coming, or what?"
