In the past, we have done a lot of work to make (and keep) Cuyahoga compatible with Mono. But mostly due to time constraints, we have not been able to keep up with recent Mono versions. The current state is that the Cuyahoga 1.5.1 sources build fine with NAnt (Mono 1.2.6 from the VMware image), but it just doesn't run.
So it would be great if anybody with a little Mono experience (and time :)) can help us out with this. Volunteers?
