 Oh ... so I could just use `system port select .....` from the Portfile if
 it detects that the call hadn't been made? O:-)

 Because the majority of users are on 10.6? I don't see how else you
 reached that conclusion?

 With difficulty, that's what has been the greatest hurdle. On 10.6 . On
 later OS X versions xcrun is "clever" enough to realise it shouldn't try
 to find a full path in the Xcode toolchain, but the 10.6 xcrun errors out
 when it is handed a full path. So yes, you can tell it to do that, but
 either it will result in an error or else you'll still get the Xcode
 version.
