The configure call in the ebuild for gnome-power-manager-2.20-r1 passes
parameter --enable-keyring. This is no longer present in the source. AFAICT,
--enable-actions-menu doesn't do anything either:
cbm@aconite ~/src/gnome-power-manager-2.20.0 $ ./configure --help | grep action
cbm@aconite ~/src/gnome-power-manager-2.20.0 $ ./configure --help | grep key
cbm@aconite ~/src/gnome-power-manager-2.20.0 $
In previous versions (at least 2.18), --enable-keyring actually did something
which I didn't want (namely locking my keyring on hibernate). However, it
seems in 2.20 this is controlled by gconf keys rather than at configure time:
/apps/gnome-power-manager/lock/gnome_keyring_hibernate
/apps/gnome-power-manager/lock/gnome_keyring_suspend
