I guess your pkg-config claimed that you have a working libpng, even though you don't. Try running the following shell commands: pkg-config --cflags "libpng >= 1.0.0" pkg-config --libs "libpng >= 1.0.0" If these commands tell 'configure' to use flags like -lpng12 but those flags don't work, then you have a problem with your pkg-config installation somewhere. Although you can work around the problem by building Emacs with './configure --without-png', it's better to get your png installation whipped into shape.
