This looks nice, and can be the way to go. But one flaw yet to be
plugged: it has no idea of "optional dependencies". pango is a good
example -- it can build with only glib 1.3.x, yet it can optionally
include external fribidi library. In this way, fribidi library won't be
listed as BuildRequires, since pango can build without it.
