      For best results, you will want to install the latest version of XQuartz:
        http://xquartz.macosforge.org/

      You may also want to get winetricks:
        brew install winetricks

      Or check out:

        The stable version of Wine is very old. You will get better results with
        the development version. Use:
          brew install wine --devel
