That’s a dependency problem, which is orthogonal. A model like Nix can make this work splendidly. The programs that share an exact version of a shared lib do share it, but you are free to use a custom dynamic lib for only one package. In a way, Nix makes your notion of “clojure” the way of life everywhere (not just binaries, but scripts as well referring to interpreter, other programs by explicit hash of derivation)
