[gtk-osx-users] LibXML2 site-packages configuration.

[Pascal <p p14 orange fr>]

Hello,

As the jhbuild Python version has changed to 3.10 and moduleset Python version is still 3.9, when building 
Python and GTK, LibXML2 is puzzled to find the good site-packages folder.

/usr/local/xnadalib-2021/lib/python3.9/site-packages
and
/usr/local/xnadalib-2021/lib/python3.10/site-packages
are both present in prefix.

LibXML2 is installed in the latter :-(

I propose some changes:

     _python_install_path = os.path.join(prefix, 'lib', 'python' + _python_ver,

Maybe some cleanup is also needed.

What is your feedback?

Thanks, Pascal.
