I missed one line here: "Hard(est) because you have to communicate with dynamic linker." For eg RInside we do that and encode the path via rpath, but that is eg frowned upon by Debian because it makes your binary (or library) non relocatable as those paths remain fixed../ | > System shared libraries is easy (just ask all the database packages, graphics | > formats packages etc pp) -- but you then push the burden onto your users to | > actually *have* these system libraries.

Sadly, it really is hard, and made harder by the fact that we have some many choices -- and then OS-depedencies. I have been thinking about creating a tutorial for Rcpp users on this but so far have not yet figured out how to do it all well enough to be worth it.
