I'm trying to use the Html Agility Pack with a MonoTouch application, but cannot find a version that will work with it.

I downloaded the latest binaries from [CodePlex](http://htmlagilitypack.codeplex.com/releases/view/90925) and I've tried building with every DLL it contains. None will compile when the target is the iPhone.

Adding the .NET 20 library will allow it to compile to the iPhone Simulator, but when switching to the iPhone I get the error:

```
Error MT2002: Can not resolve reference: System.Diagnostics.TraceListener (MT2002) (MFLPlatinum12)

```

It seems like others are using HtmlAgilityPack with MonoTouch projects, so any thoughts as to what I'm missing?
