Bugzilla Bug 158614

gnome-bluetooth-0.8.0 doesn't quite work so I downgraded to 0.7.1-r1, which
wouldn't compile (too few arguments to function
`btctl_controller_discover_devices') and other errors.  googling led me to also
downgrade libbtctl to the previous version, 0.6.0-r1, which enables
gnome-bluetooth 0.7.1-r1 to compile and install cleanly.

(Note gnome-bluetooth 0.7.1-r1 doesn't exhibit Bug 157600.)

the gnome-bluetooth-0.7.1-r1 has the dependancy 
        >=net-wireless/libbtctl-0.6.0-r1
but perhaps it should be
        =net-wireless/libbtctl-0.6.0-r1


So, in summary, this works:
net-wireless/gnome-bluetooth-0.7.0-r1
net-wireless/libbtctl-0.6.0-r1

this doesn't:
net-wireless/gnome-bluetooth-0.7.0-r1
net-wireless/libbtctl-0.8.1

I'm marking this as a duplicate of the other one, because ideally that's what
you want to do is use the later libbtctl which fixed the sanity check (see
http://bugzilla.gnome.org/show_bug.cgi?id=372454)
