... but I can't really find through which module.
Looking at libcap's "required by" in testing, I thought I would only need to reinstall proftpd, avahi, samba and wireshark. But I had to upgrade mplayer and mpd too. So this is just a question, maybe mplayer and mpd lack "libcap" somehow in their PKGBUILD ?
And by the way, it seems lirc is a little bit old in testing :
