Hi David I am a long time user of ghc on OSX. I have seen that problem but never on native OSX only when using nix (and then I added it explicitly).
Two things spring to mind: Add it explicitly on the compile command `-liconv` Use nix and then you can control the build environment in a totally controllable and reproducible manner. This is actually easier than it sounds: `curl https://nixos.org/nix/install | sh` and `nix-env -I ghc`. If you get the same error with that then we can try adding `iconv` explicitly.
