10 years ago I have tested this now with Ubuntu 14.10 dev and libpng-dev and zlib1g-dev are dependencies of other packages there:

The README.md says on Ubuntu:
On my system (Ubuntu 12.04 dev) zlib1g-dev is a dependency of libpng-dev. This means that zlib1g-dev can be removed from this line because it will be automatically installed. But first we should test if zlib1g-dev is a dependency of libpng-dev in all currently supported Ubuntu versions.
