Issues compiling upower 0.99.4 in mint 17.1 / ubuntu 14.04

[Andreas Donath]

Hello,

	My initial problem:
	I use a Logitech K760 Bluetooth keyboard
	on Mint 17.1.

	The power indicator of the cinnamon desktop
	always complains, that it would be completely
	discharged at 0%.
	
	The applet seems to use org.freedesktop.UPower,
	and a
	"upower --dump" reveals:
	
	Device:
/org/freedesktop/UPower/devices/keyboard_hid_00o1fo20o3eo1eoc4_battery
  native-path:          hid-00:1f:20:3e:1e:c4-battery
  model:                Logitech K760
  power supply:         no
  updated:              Tue 16 Jun 2015 02:59:44 PM CEST (14 seconds ago)
  has history:          yes
  has statistics:       yes
  keyboard
    present:             yes
    rechargeable:        yes
    state:               discharging
    percentage:          0%


	The installed (by default) version of upower is:
	0.9.23-2ubuntu1

	So I thought I would compile a newer version, hoping that
	the device will be correctly recognized.
	
	I checked out version 0.99.4 from github but autogen.sh fails.

autoreconf: running: automake --add-missing --copy --force-missing

./configure: line 3138: syntax error near unexpected token `0.9.9'

	Do I miss something, or is this the complete wrong appraoch?
	What can I do here?	
	Any help would be highly appreciated.

Cheers
Andreas
