As you can see in the section "Requirements" of the INSTALL file:

  The PNG Reference Library ("libpng") must be installed.
  Libpng is available at http://www.libpng.org.

You need to install libpng. Most probably you'll nedd to install the 
development package for libpng using the package manager of your distribution.


Best regards,
Antonio.
