# gnome-base/gnome-common required by eautoreconf

# We now disable introspection support in slot 2 per upstream recommendation
# (see https://bugzilla.gnome.org/show_bug.cgi?id=642048#c9); however,
# older versions of slot 2 installed their own site-packages/gi, and
# slot 3 will collide with them.
