Compiling beagle on mono 1.2.6

Hi,

I had tried to compile beagle on newest mono (version 1.2.6). All
related packages of mono were updated to (e.g. gtk-sharp, etc). But
beagle doesn't compile, here is the error:

I had tried the CVS version of beagle and the latest source tarball
(version 0.3.1). Both version don't compile on newest mono.

Any suggestion?
