`/opt/local/bin/wine-preloader` is not present, right?
Correct
Also you must have done this somehow, but you ran `autoreconf` to regenerate `configure` and `include/config.h.in`?
Yep I ran `autoreconf -i` so both `configure` and `include/config.h.in` were both updated correctly, even downgraded my copy of `autoconf` to match the one used by the Winehq actions.
