Hi @bipsBro

This error usually occurs when a required library is not installed on your system.
As far as I know, libpng16-dev is required by the png optimization package but it isn't pre-installed on every system. Can you try to install it and test it again? I think you should be able to do it on ubuntu with apt-get install libpng16-dev.
