This problem is really serious, I think you should consider a 
release sooner.

I am trying to get started with `dub` but this issue keeps 
popping up.

All I did was this:

```
dub init myproject
dub add silly
dub build
```

silly is a nicer test runner, which is exactly what I wanted... 
but the build fails with linker issues:

     ▶ dub build

Unless silly is completely broken, it seems like this is a linker 
issue again.
