I had Xcode 3.2.3 installed with the "Mac OS X 10.5 Core Library" and "Xcode 3.2 Developer Tools Library" document sets fully downloaded. Then I had to re-install Xcode with the download from developer.apple.com, in order to get the iOS SDK.
The previous "Mac OS X 10.5 Core Library" and "Xcode 3.2 Developer Tools Library" document set files are still there in my Developer directory -- current as of yesterday -- but Xcode is now trying to re-download them (1.5GB over my slow connection).
Is there any way for me to cancel this, and get Xcode to recognize the existing document sets (and without messing up its automatic updates)?
And I'm wondering -- since these document sets seem to be giant single files on disk, if I'm going to be having a 4 hour/2GB download every few days when something minor gets updated in the documentation...??
