I'll check our other suggestions, but this seems like the main issue.
I got something working by patching libgpiod:

I guess the reason is something with that the python compile options
from ptxdist in ptxd_make_world_compile.sh isn't being passed
correctly, probably because it is a python3 build within a autoconf
env.
I don't know if this is the correct way to fix it.
