That looks fine. Looks like OS X 10.8.2 to me.

So that Xcode Preferences screenshot you sent. Was it created on this OS? If so 
what does it say when you choose About Xcode from the Xcode menu?

Ok, perhaps if you show us that main.log it might shed some more light on the 
problem.

If you haven't already seen it, this is our page describing the steps needed 
after such an upgrade:

Ok, good. I don't remember exactly what I did when I upgraded from 10.6.8, but 
I assume I would have tried that, and my old Xcode did not get properly 
removed, and I had to manually hunt for and delete things. In particular, 
although the new Xcode 4.x was in /Applications where it was supposed to be, 
the old Xcode 3.2.6 was still in /Developer/Applications and I had to trash it 
and everything else in /Developer manually. Maybe you could have a look there 
as well.

Ok; you could also have installed from the Mac App Store, but manually 
downloading it from ADC is fine too.

That's correct: that's the actual Xcode application, not an installer program.

That's the correct thing to do, yes.

Yes, these days the Xcode.app itself contains most of the things that used to 
be in other locations in /Developer.
