There already is media-gfx/pngcrush and pngout is not Open-Source, but it compresses better than pngcrush and others. PNGOUT optimizes the size of .PNG files losslessly. It uses the same deflate compressor the author wrote for KZIP. With the right options, it can often beat other programs by 5-10%. That includes pngcrush -brute, optipng -o7, advpng -z4, etc.. PNGOUT is a great tool for optimizing the size of web pages or squeezing game content onto mobile devices.

Mhh, how do I assign this bug to maintainer-wanted@gentoo.org ?
Please read the description for what the "Keywords" field means. EBUILD is for already-provided ebuilds, REQUEST is what you need here. Ordinary users don't have the possibility to re-assign bug themselves, IIRC.
Sorry, but this is a case of WONTFIX because pngout is compiled against libpng 1.2.x by upstream and no version available which is linked against libpng 1.4.x. Just use pngcrush or optipng.
