It looks like it's able to use inotify directly without needing to rely on old gamin/fam for that. That is the way chosen by Debian as I saw in their changelog: http://metadata.ftp-master.debian.org/changelogs/main/k/kcoreaddons/unstable_changelog (search for "fam") Adding the mask to default/linux/package.use.mask should be enough then Thanks
Thanks, fixed in git. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=4e4ad4e26c19bccb91426290a726ce6fec4d3167
