Are the modules in this folder tested by the CI?

I'm trying out this file in v2.103.0: 
https://github.com/dlang/dmd/blob/05e91cdcf88a922465ff3604e28f54dc385d7f65/compiler/test/dub_package/lexer.d

```
$ dmd --version
> DMD64 D Compiler v2.103.0

$ dmd app.d
app.d(3): Error: unable to read module `globals`
```

It does not seem to work.

Maybe I could try with DMD `master`. Although `digger` no longer 
seems to work so I bet it's gonna be a pain building everything 
from scratch.
