Hmmm.  I have Xcode 4.6.1 (4H512).  But AppleMenu->Software Update… shows that
only iTunes is available for update (to v 12.1).  My O/S is 10.7.5 (Lion).  What version is
yours, Jeremy?

@René: If I need to, how can I update my Xcode?  Or my version of Lion, if Jeremy has
                a later version of that, too?

Cheers, Ian W.
