I had to add some things to make this work: - acpi-linux.h is missing in the main-archive, it won't compile without it. - battstat-acpi.diff is needed for the applet to work with the new kernel acpi-system (www.sourceforge.net/projects/acpi/)
Created attachment 1447 [details] ebuild for battstat-2.0.13
Created attachment 1448 [details, diff] patch to make it work with new acpi - place it into files-directory
Tested & Committed, thank you. - stroke
