 Ok. I may look into this in the next days if nobody else beats me to it.

 > More generally, we need to be cautious about switching to Python 3.12,
 particularly for foundational ports like this. (Just a general suggestion,
 to avoid having to scramble to fix issues.)

 Evidently! This distutils thing seems like one big easy-to-overlook
 problem (it occurs with gobject-introspection too in #69105), and syntax
 warnings due to lack of use of raw strings is another big one I've seen
 several times already in other ports. I was trying to be helpful but I
 should have remembered that I don't understand Python so I've discontinued
 my effort to switch ports to Python 3.12 and will leave it for those more
 knowledgeable.
