A new bundle is being uploaded as we speak. The DMG image fairly large, but this appears to be because of all the extra libraries brought in with the OSXbuilder (http://code.google.com/p/osxwinebuilder/) for added functionality.
Give it a try and let me know if there are any issues. This is an initial release so expect an improved app and installer. Expect source code and ANT script for the bundle soon.
