Current versions available from bluez.org are at 3.7. Current version in portage is 2.25.
bluez-libs installs OK with a simple version bump of the ebuild. Currently trying to get bluez-utils installed...
Created attachment 102825 [details, diff] bluez-utils-3.7.ebuild - removed reference to gtk (bluepin is now part of bluez-gnome) - added fuse USE flag - now depends on dbus. I could not find any documentation but it looks like dbus is no longer an option but required (the configure script does not allow you to enable or disable it).
