I guess what the sentence "Please install libpng or libpng-dev packages"
really wanted to say "Please install libpng or libpng-dev package".

You have two options:
Either you install libpng from source (the better, imho) or you can add
the pakage libpng-dev (of course, this depends on libpng package so this
is not mentioned). 

The thing is that if you compile libpng from source, you get the
libraries libpng.* and all the necessary files in order to COMPILE
comething using libpng, and of course run anything compiled against
libpng.

If you install the libpng package, you can run anything PRE-compiled for
you that is linked against libpng, but you lack the necessary files to
compile something of your own... those files are in libpng-dev package.

This applies not only to libpng but to all packages

hope i helped.
