The significant runtime dependencies apper to be glib, dbus, polkit, udev, libusb, pm-utils. The oldest upower I was able to find information for is 0.9.2, from April 2010. It wants at least: glib 2.21.5 dbus-glib 0.76 polkit 0.91 udev 151 pm-utils 1.3.0 The most recent I was able to find was 0.9.21, which wants: glib 2.22 dbus-glib 0.100 polkit 0.110 udev 200 pm-utils 1.4.1 (or systemd 200) I don't know what minimum version our hardware lib requires.
