VisualD and dub imports - module X is in 'X.d' which cannot be read

[Geoff Howland via Digitalmars-d-ide]

Hopefully this is the right forum to use for this question, Im 
having a problem with VisualD and dub builds.

I made a simple vibe.d project with Dub, it works from CLI and in 
VisualD.  When I add the "dyaml" package to dub.json, the CLI 
still works, but the VisualD compiler gives me this error "module 
yaml is in file 'yaml.d' which cannot be read".

I cant find where dub is putting the dyaml package, and while I 
found some related answers in forums and SO, but I didnt find a 
solution to this.

Anyone know how to solve this?  Does dub download the yaml.d file 
and put it someplace?  It doesnt seem to be under the project 
directory I created, and it also isnt in the sparse dub directory 
that the windows dub installer creates.

Things I've tried:

- Finding where yaml.d is put by dub, so I can include it in the 
build.
- Looking through the .dub directory for anything that looks 
related to this.
- Searching through the forums here (via Google) and Stack 
Overflow.

Any help would be appreciated.
