I have an arm64 gentoo install on a RPI3. Package app-admin/sysklogd has no arm64 or ~amd64 keyworded versions in current portage tree. Here's how the emerge went: james@raspberry:~$ sudo FEATURES="test" emerge -av1 --nodeps sysklogd These are the packages that would be merged, in order: [ebuild R *] app-admin/sysklogd-1.5.1-r1::gentoo USE="-logrotate" 0 KiB Total: 1 package (1 reinstall), Size of downloads: 0 KiB Would you like to merge these packages?
