"libpng". Somehow or other this didn't work out. If you don't have
libpng on your system, sorry but you need to install this module. 

If you are on Ubuntu Linux, you probably need to do something like

    sudo aptitude install libpng-dev

to install the header file "png.h" for libpng into your system.

If you think you have libpng on your system, please edit the file
"inc/CheckForLibPng.pm" and run "perl Makefile.PL" again. The relevant
lines are right at the top of the file,

my $png_lib_dir;
my $png_include_dir;

Edit these lines to wherever your libpng and png.h files
respectively are to be found, for example

my $png_lib_dir = '/some/strange/directory';
my $png_include_dir = '/somewhere/nobody/knows';
