This means the guetzli executable was compiled on a machine with Libpng 1.6 installed, but is run on another machine that doesn't have the same Libpng 1.6 installed.

You either need to install Libpng 1.6 on the machine where you run it, or compile the executable again, but with libpng linked statically.

This is not specific to guetzli, so you can look for tutorials about using libpng in general.
