This is version 1.2.x of libpng, while libpng-version's value, 10403,
means that Emacs looks for version 1.4.3 or later. If you evaluate
`(image-type-available-p 'png)', you should see nil.
You need to download a newer version of libpng.

Sorry, it was 6AM outside and cold, so my brain didn't warm up yet.

You will find libpng 1.4.x here:

With this newer version, PNG support should work. You may need to
restart Emacs, though (but I'm not sure, so try without first).
