I think there's an issue with dub / visuald (not dagon), but how can I get dagon Tutorial1 Simple App to build?

I posted this issue in the GitHub issue tracker:

https://github.com/gecko0307/dagon/issues/100

But it looks like it has something to do with dub changing folder 
structure (so that the shaders folder isn't immediately where it 
should be).

Any idea how to fix this?
