Arduino Zero / IDE 1.6.5 : fatal error: avr/power.h: No such file or directory

Hi,

i got the new Arduino Zero and i downloaded the Arduino IDE 1.6.5 but i cant compile anything which use avr libs.

strandtest.ino:2:23: fatal error: avr/power.h: No such file or directory
compilation terminated.
 ; locate power.h | grep avr
/home/noxictonic/Apps/arduino-1.6.5/hardware/tools/avr/avr/include/avr/power.h
/usr/avr/include/avr/power.h

how can i fix this error?

I hope this is the right forum for that topic
