I'm new to nix and macOS dev am not sure what to do. I will use a different computer for now.

The switch in the code is very rudimentary with isDarwin and doesn't takes CPU arch into consideration. This said, a lot of the upstream repositories still aren't building binaries for ARM currently either (this includes all OSs--not just a macOS issue) so it's not like easy-purescript-nix could fetch them anyhow. Anything doing with building from source is not in this repo because it ventures outside of the "easy" part in the repository's namesake.

I'm sure we would all love to see better ARM support, but it's still not here yet.
