Current release is version 20060907, portage only has 20030713. After copying the ebuild from libuninameslist-20030713.ebuild to libuninameslist-20060907.ebuild, edit the SRC_URI and replace the ${PV:2:6} with just ${PV}, since the filenames have since switched from two to four digit years. I've tested with that change, and it works as designed. media-gfx/fontforge needs this to correctly describe newer unicode characters while editing fonts.
