Setting HtmlAgilityPack to work with Mono for Android

I've asked a similar question before, but nobody answered. How do I set HtmlAgilityPack to work with Mono for Android? I've added reference to .dll but when trying to use HtmlDocument I get error that

System.Xml version 2.0.0.0 or 4.0.0.0 is missing.

But there is a default reference to System.Xml version 2.0.5.0. And if I reference 4.0.0.0 it works, but then some of the Mono for Android things don't work. A user here gave me an Android specific version, but it seems that it doesn't contain HtmlWeb, which means it's useless. How do I set HtmlAgilityPack to work with Mono for Android?
