I think we should wait for a fix on libpng However it could be fixed by running optipng -fix ui_minimap.png optipng -fix ui_bpanel_200x264.png optipng -fix ui_info.png You can get optipng by running emerge optipng fixing dosn't seem to work here would be interesting if this due to illformed pngs by boswars or due a bug in libpng? As in eigther case it comes down to something that can't be solved in distribution scope alone. A quick look didn't show me up an matching bug against libpng 1.6.3 on libpngs bugtracker. that is a known issue, libpng-1.6 is just stricter so it is an corrupted png by boswars, is there a way to correct a png, maybe they are faster in fixing this when there is some suggestion, btw the original files seem to be unchanged since 5 years in their svn e.g. svn export svn://bos.seul.org/svn/bos/bos/trunk/graphics/ui/ui_minimap.png gives the file, this could indeed be fixed by optipng, but result is a close to complete black image.

boswars-2.7-r1.ebuild.diff
there is a tool shipped with libpng-1.6.3 that helps out I made a small bashscipt to fix boswars files (executed as root in /usr/share/boswars)
for i in $(find . -iname '*.png'); do pngfix -q ${i}; if [[ $? -eq 1 ]]; then echo ${i} broken ; pngfix -q --out=${i/.png/_fixed.png} ${i} ; pngfix -q ${i/.png/_fixed.png} ; if [[ $? -eq 0 ]]; then echo "${i} fixed successfully" ;mv ${i/.png/_fixed.png} ${i};fi; fi ; done
