My apologies for not getting back to you earlier wrt the python
bindings.
When I try them I get:

$ python3
Python 3.9.2 (default, Feb 28 2021, 17:03:44)
[GCC 10.2.1 20210110] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import gpiod
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "exception.c", line 1, in <module>
NameError: __build_class__ not found
>>>

I may be doing something dopey, but building v1.6.3 on the same
platform (a clean Debian 11.3 install with a v5.18 kernel with gpiosim
and gpio-mockup) works fine.
Haven't had a chance to look into it further...

Any ideas?

Cheers,
Kent.
