By default (unless you pass an explicit --binpkg-respect-use argument), portage will warn you when it rejects a binpkg which is incompatible with your system, and tell you what USE flags you could change if you wanted to get a valid binpkg match. There are definitely some binpkgs for qtwebengine, depending on which USE flags you need (or are willing to compromise on). It may take up to a day for binpkgs to appear after a new version hits stable. Our scheduled jobs start once a day at 9:11 AM UTC and build whatever version is the default at that time. Days with lots of updates can mean a delay in binaries being built. A few days ago I improved this to incrementally upload packages once per hour instead of only at the very end. > Secondly, what is the life expectancy of any given binpkg, storage capacity > being finite? Packages are *only* removed by running eclean-pkg with the defaults. This means that packages are only removed once the ebuild that built it has been deleted from the ::gentoo repository. -- Eli Schwartz
