Okay that makes sense. I’ve taken a closer look at the two Makefiles and see that they are indeed similar - the key difference being that elixir-devel depends on an erlang runtime rather than lang/erlang, and that it patches the elixir script. I will experiment with removing the post-patch hard-wire from elixir-devel. I believe when I did that, elixir failed to run because there was no erl on the path. lang/erlang puts erl on the path, but erlang-runtime* do not. If I’m remembering correctly. Pathome | help
