Comment (by cjones051073):

 b.t.w. you are correct *some* ports can be built without having Xcode
 installed. However, as the warning above notes not having it installed is
 likely to cause problems. If you have happy to live with this, fine,
 that's up to you. Otherwise just install Xcode.... Your choice.
