Link seems broken to me. We'll have to ask Lluis for an updated link.

Sorry, no idea what the problem is. It looks like the GTK# code
generator is funning for some reason - and failing, generating broken
but compilable code.

It might be possible to build with xbuild, if you use Mono 2.4.3 or
2.6.x, which would avoid the GUI regeneration. Alternatively, you
could extract MD from the openSUSE rpms using an archiving app such as
7-Zip, and build just the WindowsPlatform addin by hand. Or perhaps
you can find a way to force the MD installer or extract the files from
