in a nutshell, rpaths are relative paths, telling the linker to search for extra dependencies, written into library/executives binaries, and allow you to avoid depending on the execution environment; apparently it's very easy to create on Linux, but not so on OSX, where you need to jump some hoops. People wrote tools to fix the latter, such as https://github.com/auriamg/macdylibbundler/ Thus, it would mean no more runtime linking to a wrong library due to wrong (DY)LD_LIBRARY_PATH and the latter doesn't work (at all?) on OSX11, as far as I understand.
