sys-auth/policykit is obsolete, and should be removed from tree. replaced by sys-auth/polkit.
As for the rest in: http://tinderbox.dev.gentoo.org/misc/rindex/gnome-extra/policykit-gnome http://tinderbox.dev.gentoo.org/misc/dindex/sys-auth/policykit hplip -> is fixed policykit-qt and policykit-kde -> are masked for removal by approval from KDE team so that leaves old gnome, old networkmanager/nm-applet and the --disable flag for HAL
OK, now this can be done after latest revision of HAL is stabilized. Let's give it some time then ...
policykit is no more, but will leave the mask message in place for now and remove it later.
