RhinoMocks breaking the compiler in recent versions of Mono / MonoDevelop

Question

I'm not sure exactly what broke this as I've been sporadic with my Mono/Monotouch development, but I believe it's the latest update to the mono framework. All of a sudden building my Unit Test project (which itself is a MonoTouch Library project) now breaks the compiler and it seems to be the RhinoMocks DLL (removing the reference fixes it). It looks like the RM DLL is referencing the wrong System DLL (not the MT one) but what is confusing is why this never broke before and my tests used to run fine.

I've put a simple sample SLN up on Github that reproduces the error: https://github.com/briandonahue/MonoIssue

And here is the build ouput:

Answer 1

Seeing the same thing with mono 2.10.1 and monotouch 4.0 on the simulator. But only when Linker options are set to link all assemblies.

Works fine with Linker options set to don't link or Link SDK assemblies only.
