>Description:
	When attempting to launch quodlibet (4.6.0bn10), quodlibet dies with an
	error saying `No module named 'senf'`. senf is included with quodlibet
	under `/usr/pkg/lib/python3.12/site-packages/quodlibet/packages/senf`,
	but quodlibet/python does not attempt to search for modules under that
	path.

	My system has two different versions of Python installed, both from
	pkgin: 3.12 and 3.13. quodlibet using 3.12. Do not know if that
	information is relevant.
>How-To-Repeat:
	Install the audio/quodlibet binary package using `pkgin` and attempt
	to execute quodlibet from the command-line. The following error appears
	for me:

	    Traceback (most recent call last):
	      File "/usr/pkg/bin/quodlibet", line 11, in <module>
	        from quodlibet.main import main
	      File "/usr/pkg/lib/python3.12/site-packages/quodlibet/__init__.py", line 21, in <module>
	        from .util.i18n import _, C_, N_, ngettext, npgettext
	      File "/usr/pkg/lib/python3.12/site-packages/quodlibet/util/__init__.py", line 28, in <module>
	        from senf import fsnative
	    ModuleNotFoundError: No module named 'senf'
>Fix:
	A work around is to manually point PYTHONPATH to the directory where senf
	is installed.

	    PYTHONPATH=/usr/pkg/lib/python3.12/site-packages/quodlibet/packages \
	      quodlibet

	(after that, quodlibet fails with the following errors, but I do not know
	if those would be within the scope of this issue)
