From portage/profiles/base/package.use.mask: # Tom Wijsman <TomWij@gentoo.org> (02 May 2014) # Bluetooth support in MATE has incompatibilities with recent BlueZ versions. # If you want to try to get this working, unmask net-wireless/mate-bluetooth as # well as the bluetooth USE flag on mate-extra/mate-user-share; I can't support # this until the relevant upstreams have moved forward with their compatibility. # # https://bugs.gentoo.org/show_bug.cgi?id=508086 # https://github.com/mate-desktop/mate-bluetooth/issues/22 # http://mate-desktop.org/blog/2014-03-11-mate-desktop-singing-the-bluez mate-base/mate bluetooth mate-extra/mate-user-share bluetooth The oldest version in tree (1.10.0-r3) is ported to Blueman and BlueZ5, net-wireless/mate-bluetooth has been removed. This USE mask is obsolete, please remove.
