I then rebuilt gobject-introspection and then librsvg built OK.
AFAIK there is no relationship between rust and gobject-introspection.
My question is how to address this, or whether we should address it in
the book at all?
This looks like a problem with upgrading from Python-3.7 to Python-3.8.
/usr/bin/g-ir-scanner on line 99 references scanner_main which is
compiled for the major version of python3 in use at the time - which in
our case was python3.7. Since we upgraded to python3.8, we'll need to
recompile gobject-introspection.
