I've just read the Marek feedback from https://bugzilla.xamarin.com/show_bug.cgi?id=5342 and it turned out that the build failed due to simple typo. After correcting that it compiles fine on my Linux system.
Fixed typo which failed build on case sensitive systems.
could you review this patch? It should be rather straightforward.
Let me have a look. On my unix box it's not a typo. Which mono version you using?
Well, I have mono compiled from the mono repository, specifically commit 6dbd060, so quite new (also known as 2.11.2), although this is simply mark of the beta version). If you have some real compiler errors on the latest stable, then they were probably resolved in the meantime. Nevertheless the file casing will cause problem anyway ;)
