Turns out it is simply a missing RDEPEND.

Nevermind, reported it upstream. http://bugs.gentoo.org/show_bug.cgi?id=348951 Thanks for reporting it
checking now, using my laptop where i still have this problem, because i do not upgrade so often my system and i do not use smartd service so often: sudo rc-service smartd start * Starting S.M.A.R.T. monitoring daemon ... /usr/sbin/smartd: error while loading shared libraries: libcap-ng.so.0: cannot open shared object file: No such file or directory * start-stop-daemon: failed to start `/usr/sbin/smartd' [ !! ] * ERROR: smartd failed to start time sudo equo update sudo equo --info | grep "Database revision" Repository databases: sabayonlinux.org => Database revision => 2138 time sudo equo install smartmontools >> @@ Calculating dependencies ... >> ## [N] [sabayonlinux.org] sys-libs/libcap-ng-0.6.2|0 >> ## [U] [sabayonlinux.org] sys-apps/smartmontools-5.40|1 [5.40|0] . . blablabla . . sudo rc-service smartd start * Caching service dependencies ... [ ok ] * Starting S.M.A.R.T. monitoring daemon ... [ ok ] yes, i can confirm, problem solved from sabayon and entropy infrastructure point of view ... also in upstream gentoo portage tree is solved and changes already pulled in by a new smartmontool entropy package, smartmontools-5.40|1 ... for sabayon users with this problem is only a need to update entropy database and reinstall smartmontools ... for those sabayon users who frequently upgrade their system this bug can fly away unnoticed ... ;-)
