I ran into this yesterday, and google explained it. The problem is that you 
need the latest XCode, 4.4, but the update does not appear in the app store 
when you check for updates. Instead, find XCode on the app store and download 
it again. Once it installs, launch it (the one in /applications, not the one in 
your developer folder). It will download some needed component, then take you 
to a screen where you can delete previous versions. This removes the developer 
folder, and maybe a couple others as well, so make sure you save everything 
important in /developer before continuing if you decide to uninstall old 
versions as I did.
