Just a hint - extra attributes in the `mkShell` appear as environment variables in the built shell. So instead of a `shellHook` for this you can just have an attribute `ERL_LIBS="";`
I'm not completely sure but I think this approach is preferred because shellHook only runs in `nix-shell` but if you ever wanted to `nix-build` a release it might not run.
