Static Library fails to build under Xcode 4.2 (Build 4C199) with numerous Semantic Issues, probaly to many to list here. I'm using latest commit from March 15.
Previously DTFoundation from 5/12/2012 compiled successfully under my setup. I can't upgrade OSX and Xcode just yet.
Please fix them and submit a pull request, I don't have a previous Xcode any more
