   🙏  Some combinations of things I tested locally, with a dev build of arrow in `ARROW_HOME` and having done `brew install apache-arrow`:
   
   * Usual way, with `ARROW_HOME` set: you see the new message warning you that you're on dev versions and if the build fails, update your C++ build
   * Edit the version number in `"$ARROW_HOME/lib/pkgconfig/arrow.pc"` and see that it is rejected because the versions don't match.
   * Unset `ARROW_HOME`: Homebrew apache-arrow is found, but it fails the version check, so it isn't used. Since we're on a dev version, autobrew isn't attempted and instead the bundled build starts (I ctrl-C'd though, not wanting to wait for it).
   * Put `"$(brew --prefix apache-arrow)/lib/pkgconfig` on `PKG_CONFIG_PATH` and see that `pkg-config` finds it (but then it is rejected because the versions don't match)
