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:

I went too fast on that changes, GTK build is broken, so I propose to merge both environnements if Python3 is installed in prefix:

Is it not too much confusing?

Definitely too confusing, see my comment on the other thread.
