I thought about that, but no. It really needs libpng15, specifically.
Remember it will also add -lpng15 and other versioned stuff. I don't
want to think about doing a build that uses cairo asking for png15 while
using png16 for the current source.

I don't think so. I checked, it's the same with CentOS 7.1. It's just
the way it's done is a mess. I don't believe many distros try to do what
we're doing, having two different versions concurrently.
