Hello John,

I ran again all the installation (2022b) from the beginning but I got the same error.
My configuration:
Prefix is /Users/me/2022b/xnadalib-2022

The offending file si libxml2mod.so imported by libxml2.py:
% ls ./xnadalib-2022/lib/python3.10/site-packages

But this file is well bound against Python 3.10:
% otool -L ./xnadalib-2022/lib/python3.10/site-packages/libxml2mod.so
./xnadalib-2022/lib/python3.10/site-packages/libxml2mod.so:

I provide these details in case that they might help.
Else what could help?

Thanks, Pascal.
