Trying to understand the question...
"I'm editing some source code for a script. The guy who programmed it used Tk::PNG and Imager::File::PNG to make the icons for the items in the inventory, since the games uses .tga files with alpha channels.
My problem is that I downloaded zlib and libpng (the first link on each page, marked "Setup") and installed them to C:\Program Files\GnuWin32. Now when I try to use CPAN in the command prompt, I type "install Imager::File::PNG", and I get this."
