Hm, maybe I'm mis-remembering and I in fact copied the SDK from a backup of 
an earlier installation of Xcode; maybe I just downloaded the Command Line 
Tools from the Apple site.
I'm sure I did't install any SDK from "other sources".

Ah: It's possible that the Command Line Tools actually include the SDK!
I have /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk

Sorry for being vague, I kust seem not to hav documented what exactly I did 
on my machine.
