4.1 does not have a separate PNG driver, it has a unified
PNG/JPEG/GIF driver built on top of the GD library
(libgd).  The output you show above means that gnuplot's
build process found various pieces of a PNG installation
on your machine, but they do not say anything about 
whether it found the rest of libgd.

Please check that you have libgd installed, and then try again.
You can get the latest version of libgd from
