As I somewhat hazily understand Riccardo's situation, the problem is
that everything up to gobject-introspection *has* been rebuilt and
libffi.so.8 is present.  The old gobject needs 7, and the build of the
new gobject fails because -- I think -- it is trying to use the old
installed lib.  I think Riccardo is doing "make replace".    On macOS, I
solve this by "pkg_delete -f" and then "make package-install" intead of
make replace.
