Closed issue by non-Jedi on void-packages repository

https://github.com/void-linux/void-packages/issues/6414

Description:
### System

* xuname: Void 4.19.12_1 x86_64 GenuineIntel uptodate rrrmFFFFFF
* package: xmonad-0.15_1, xmonad-contrib-0.15_1

### Expected behavior

When below is in `~/.xmonad/xmonad.hs`, `xmonad --recompile` should give no output and successfully compile (https://hackage.haskell.org/package/xmonad-contrib-0.15/docs/XMonad-Doc-Configuring.html).

```haskell
   import XMonad

   main = xmonad $ def
       { borderWidth        = 2
       , terminal           = "urxvt"
       , normalBorderColor  = "#cccccc"
       , focusedBorderColor = "#cd8b00" }
```

Additionally, the `xmonad-contrib` package should have more files in it than just the license.

### Actual behavior

With haskell snippet above in `~/.xmonad/xmonad.hs`:

```
$ xmonad --recompile
XMonad will use ghc to recompile, because "/home/adam/.xmonad/build" does not exist.
Error detected while loading xmonad configuration file: /home/adam/.xmonad/xmonad.hs

xmonad.hs:1:1: error:
    Could not find module ‘XMonad’
    Use -v to see a list of the files searched for.
  |
1 | import XMonad
  | ^^^^^^^^^^^^^

Please check the file for errors.
```

And the files in xmonad-contrib are:

```
$ xbps-query -Rf xmonad-contrib
/usr/share/licenses/xmonad-contrib/LICENSE
```

Any ideas @xaltsc?

### Steps to reproduce the behavior

1. Install xmonad.
2. Create `~/.xmonad/xmonad.hs` with config shown above.
3. `xmonad --recompile`
