Monotouch iOS binding works on iOS 6 but fails under iOS 5

I've created a Monotouch iOS binding for the latest version of the Chartboost SDK. It works fine when I run it on the iOS 6 Simulator but fails on the iOS 5 Simulator.

The error message:

NSInvalidArgumentException reason: -[__NSCFDictionary setObject:forKeyedSubscript:]: unrecognized selector sent to instance 0x11b8cce0

I've set the iOS build SDK version for my project to 6.1 and the deployment target (minimum OS version) to 4.3.

What am I missing?

[Update] I've put my binding onto pastebin: http://pastebin.com/KfTztyDP. Maybe it's some help.

I found the answer thanks to the answer by dalexsoto over here: MonoTouch "unrecognized selector sent to instance" not working on iOS5 (but does on iOS6).

I just needed to add lib arclite.a to my Monotouch binding project and it worked.

If anybody has the same or similar problem just download that library over here https://github.com/PSPDFKit/XamarinBindings/tree/master/AlexTouch.PSPDFKit and add it to your binding project.
Thanks to the new Xamarin Studio you do not need to fiddle around with dlls created by the bindings. Just add a reference to your binding project in your main project and everything is alright.

forKeyedSubscript was added in iOS 6. Do their docs say they support iOS 5, or is there a different version of the library for older systems?
