Beta Bindings
Add missing ARC runtime linker flag
We still need libarclite for iOS5 (since setting -fobjc-arc with MonoTouch is tricky)
Comment out NSOrderedSet type until it has been proxied
Comment out troubled method (out types can't be nil)
Use IntPtr for error to not crash
Properly error handling
Add workaround for another Xamarin runtime bug
