PWM not working on pin 6 and 11

Trying to get all 6 pwm outputs on a UNO to run the same frequency.

my testing sketch

#include <PWM.h>
int32_t frequency = 3500;

void setup()  { 
  InitTimers(); 
  SetPinFrequency(3, frequency);
  SetPinFrequency(5, frequency);
  SetPinFrequency(6, frequency);
  SetPinFrequency(9, frequency);
  SetPinFrequency(10, frequency);
  SetPinFrequency(11, frequency);

  pwmWrite(3, 50);
  pwmWrite(5, 50);
  pwmWrite(6, 50);
  pwmWrite(9, 50);
  pwmWrite(10, 50);
  pwmWrite(11, 50);
} 

void loop()  { 
  delay(100000);
}


This works and gives output on port 3,5,9,10 but not on 6 and 11

same result on an genuine UNO R3 and an UNO R1(clone/compatible)

using:
Arduino PWM Frequency Library v_05.zip 
Arduino 1.0.3

extention of the library for leonardo

I wanted to extend the library for ATMEGA32U4 and ATMEGA16U4 family : Leonardo 
board.

I give you my results : 
 - a new PWM.h file
 - a CTimerDefs.h file
 - a CTimerDefs.cpp file

It seems to be good for my first tests.

But I am not be able to implement the Leonardo's specific 10-bit High Speed 
Timer/Counter4.

Hope this will help somebody ...

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
