[Mono-devel-list] mono SDL linux/win32 SDL.DLL - my brain hurts!

I got it working on the really old SDL.NET package that had Make/Build support for Mono,
I needed to put up the SDL-Dev libs too !! arggh!!! :(
But still, i'd love to be able to get a recent (this year) build for SDL.NET working,
as it looks really different (the new one) then the older one.
Also if anyone could write a small, or "point to" a resource talking to the:
"How you write a wrapper in C#/Mono/Linux to wrap a standard library in linux"
that would be appreciated.
and if someone could build the latest SDL.NET and post it somewhere that would be very much appreciated as well.
