I am currently using the Arduino Due, a Macbook pro, and have purchased a BLE shield from Red Bear labs (http://redbearlab.com/bleshield/)
I have installed their libraries, however I am having problems running their example projects. The Arduino IDE says that <avr/sleep.h> could not be found:
In file included from BLEControllerSketch.ino:16:0:
/Users/shazkam/Documents/Arduino/libraries/RBL_nRF8001/RBL_nRF8001.h:21:23: fatal error: avr/sleep.h: No such file or directory
#include <avr/sleep.h>
^
compilation terminated.
However, the avr library and the sleep.h file are included with the arduino software as can be seen from my screen shot: http://i.imgur.com/tecWrNA.png
Most of the example code that I am trying to run can be found below (I could not put all of it as characters here are limited)

I cannot seem to enable the compiler to the include the sleep.h file which is inside the Arduino app. Robtillaart has told me that the problem seems to be that the Due is an ARM processor and it has no support for AVR (atmel) libraries. I am wondering if there is a work around or someway that I can run my code. Any help on this would be greatly appreciated.
