If I recall, he was saying that you must pass
-fversion=CAIRO_HAS_PNG_SUPPORT to every file that imports it was the
problem, because you want PNG support, not stubs.

It's more an example where you need a build system in place for a simple
hello world in cairoD if you don't want to be typing too much just to get
your test program built. :)
