mono was complaining about a missing libmono-native.so, hence the pattern.
We don't provide the IKVM virtual machine, so I disabled the support. I also disabled Xen optimizations: they make mono slightly slower with the advantage to provide better performance in a Xen guest. We're a home computing distro so I think this feature is useless.
