I assume that there is some past version of nixpkgs where this worked -- would you be able to provide a pin so nix-shell works whatever the local nixpkgs version?

Your guess would be as good as mine. Clearly past me should not have been silly enough to not pin nixpkgs. Your best bet is probably a commit from nixpkgs-unstable around the time this repo was published i’m afraid.
