XamarinStudio dependency issues(Mono-D)

[Jack via Digitalmars-d-learn]

I recently downloaded Xamarin Studio from the Mono-Develop 
site(as this was the only available installer on that site) and 
was looking to try out Mono-D.

Then this showed up: http://puu.sh/8NV4V.png
Was wondering where I can get those dependencies, or how to solve 
this particular problem... Thank you
