In a Ubuntu 10.04 with mono 2.6 and in a Fedora 14 with mono 2.8 ( the two running at x64 arch)
Unhandled Exception: System.DllNotFoundException: csfml-graphics

I don't know why throws this exception, because the csfml-graphics.dll from extlibs directory is at the same directory as the executable.
I hope this error says you what happens.
