Hi.
SDL2_ttf doesn't use libpng at all, combined with the fact that you're
building the additional SDL2* packages manually is a recipe for trouble.

Maybe, but expect other packages breaking because they require newer API
functionality or decided they didn't want to deal with old libpng.

Not really, i think you're wrong in trying to manually build everything.

No, again, make the additional SDL2* packages (sic) proper packages,
that's the way, i'm pretty sure it will just work(tm) at least for
SDL2_ttf since there's no mention of anything png-related in the source.
