Currently, when people install media-libs/libpng:1.2 or 1.5 compat slots they wrongly get the old libpng news item: https://www.gentoo.org/support/news-items/2011-10-15-libpng15.html
This could be avoided by setting: Display-If-Installed: <media-libs/libpng-1.5:0 But, looking to all news item, I have seen none is using slots there, then, I wonder if that would be supported :/ Thanks for the info
