I went on the chat room on openprojects no one reported it to be working
have you, in fact, built your whatis database yet? man makewhatis :P
having said that, there was some discussion some time ago about automating the updates of the whatis database. I think it was concluded that the user might do that in a cron job or so. I've added other developers to this bug, to get their input.
Maybe the man ebuild should at least run the command or there should be a note if its not automatic must admit if i had rtfm i would have seen it
well, here's the thing, the man ebuild installs a cron file and an entry in cron.daily (it has cronbase as its dependency). so, all you would have to do is configure your cron, and this would all be taken care of anyway...
