GURU ebuild does not work

[WhitleyStriber]

The ebuild installs just fine, but I receive this error. I already tried installing gtk-layer-shell but it does not work. Is there a dependency missing or is the ebuild not setup correctly? Here is the output:

Traceback (most recent call last):
  File "/usr/lib/python3.11/site-packages/nwg_displays/main.py", line 24, in <module>
    gi.require_version('GtkLayerShell', '0.1')
  File "/usr/lib/python3.11/site-packages/gi/__init__.py", line 126, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace GtkLayerShell not available

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python-exec/python3.11/nwg-displays", line 5, in <module>
    from nwg_displays.main import main
  File "/usr/lib/python3.11/site-packages/nwg_displays/main.py", line 26, in <module>
    raise RuntimeError('\n\n' +
RuntimeError: 

If you haven't installed GTK Layer Shell, you need to point Python to the
library by setting GI_TYPELIB_PATH and LD_LIBRARY_PATH to <build-dir>/src/.
For example you might need to run:

GI_TYPELIB_PATH=build/src LD_LIBRARY_PATH=build/src python3 /usr/lib/python-exec/python3.11/nwg-displays
