[MonoTouch] System.MissingMethodException: Method not found: 'System.Type.op_Equality'.

[Sebastien Pouliot]

Hello,

Just rebuild Json.NET 4.0 Release 3 from source using the 'smcs'
compiler provided with MonoTouch. You can also look around (in git)
since some people have already built it for MonoTouch (which could
save you time).
