Hi that does make a difference,
I edited the .config file to reflect:

 <dllmap dll="msmpi" target="libmpich.dylib">

Which is appropriate for the osx dynamic library

And now when I runt he test I get:
sf-mbp:Debug stuart$ mono ./PingPong.exe

Unhandled Exception: System.DllNotFoundException: msmpi.dll
  at (wrapper managed-to-native) MPI.Unsafe:MPI_Initialized (int&)
  at MPI.Environment.get_Initialized () [0x00000]
  at MPI.Environment..ctor (System.String[]& args, Threading threading)
  at MPI.Environment..ctor (System.String[]& args) [0x00000]
  at PingPong.Main (System.String[] args) [0x00000]

So it looks like my build went weird somewhere and build a wrapper for the
MSMPI.dll and not for MPICH2 ??

Does anyone have the patch for so I can try a clean rebuild.. :(
