Comment (by mndavidoff):

 Is reinstalling cctools with the default variant a temporary workaround
 until you can fix the parse error, or are you saying I'm required to use
 the default variant on cctools? A portfile parse error seems like an
 extreme way to report the problem. If cctools +xcode is invalid, perhaps
 the xcode variant should be removed from cctools?
