Calling MonoTouch Library from Objective-C

I am using this article as a guide to call into a MonoTouch library from within an Objective-C application. We have an existing iPhone application and an existing c# library which we need to bring together. We have considered re-writing the iPhone app (Objective-C) in MonoTouch, but we do not have the time right now. We need a way to use our MonoTouch library from the iPhone/Objective-C app.

My problem is, the Xcode project generated by calling mtouch开发者_JAVA百科 cannot be compiled. It cannot find the mono header files and the .s files referenced by the project are not found because they are instead named with a .6.s extension. Am I running mtouch incorrectly? If not, how can I tell the Xcode project where the mono header files are located so it can compile? Also, how can I set up the Objective-C code to call my MonoTouch library (the main.m file has some clues, but it does not appear to be straight-forward)?

Here are the type of errors:

error: mono/jit/jit.h: No such file or directory
