Description of problem:

Cannot load module /usr/lib/pango/1.4.0/modules/pango-khmer-fc.so:
/usr/lib/pango/1.4.0/modules/pango-khmer-fc.so: undefined symbol: g_assert_warning


Version-Release number of selected component (if applicable):

rawhide pango package uses g_assert_warning (and a few others) that are only in
recent glib2 package; pango thus needs to require a recent enough version..
(or glib2 should start using symbol versions so that rpm could get this right
automatic)
