So vendoring glib is possible (we actually do it ATM, though we may revert
that). The problem is that now when you load say PyQt w/ Qt linked against
your vendored glib, you get into issues if that glib is higher than the
glib used in the system (that happens through pango IIRC). So if you want
to stay compatible, you need to build an old glib, which is what you were
trying to avoid in the first place. There is no good solution, really
