WebKit framework not found

this isn't as simple as it may first sound from the title, but i have recently reinstalled xcode 4.2 and started on my usual process of starting an app in xcode only to find that when i try to add the webkit framework to my project by going to 'build phases' then 'link binaries with libraries' as ive done many times before only to find (or not find in this case) that the webkit.framework isn't listed there, i have tried reinstalling xcode again to no avail, i have done a quick search online hoping that someone else might have had a similar problem, if they have i haven't been able to find it, is there anywhere i can download the required files and add them manually, any thoughts or advice will be greatly appreciated.
