Header in above sketch show #include <PWM.h>  PWM is blue!!! No PWM.cpp Shown

Attempting to compile shows:

PWM_lib_resolution_example.ino: In function 'void setup()':
PWM_lib_resolution_example:39: error: 'InitTimersSafe' was not declared in this 
scope
PWM_lib_resolution_example.ino: In function 'void 
demonstrateFrequencysEffectOnResolution()':
PWM_lib_resolution_example:52: error: 'SetPinFrequency' was not declared in 
this scope
PWM_lib_resolution_example:54: error: 'Timer1_GetFrequency' was not declared in 
this scope

using V5 on a Mac OS Mavericks  Arduino 1.0.5

I am a newbie, PWM shows in Contributed and when I click on it nothing happens, 
I assume that the <PWM.h> should not be blue but browny/red as per normal.

IS this a missing CPP? I have tried V4 and just keep bashing my head, its 
bleeding

Many thanks for your kind attention

I have even tried this on a Windows * machine, same issues
