I'm trying to locate the mac.h library referenced in this sketch. Can anyone point me in the right direction?
I'm using a Teensy3.1 via Arduino 1.05 on a macbook air running Mavericks. If I'm in the wrong forum, just let me know.

Code:
//version3 - 8th March 2014 - uses universeSize and requires first_universe_number
//+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
// libraries
#include <Ethernet.h>
#include <EthernetUdp.h>
#include <SPI.h>
#include <OctoWS2811.h>
#include <mac.h>
// +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
/* uses libs and open licence stufffrom many sources incl. PJRC and ArtisticLicence.*/
//this sketch is a cut down test for receiving Art-net packages via ethernet
/* ****************************************************
* To get this to work for you, YOU NEED TO CHANGE:
* 1) the mac address and IP info to same as your artnet sender
* 2) change leds per strip and universe size (universeSize is size of software output universe selected)
* 3) ensure buff2 size is large enough to take complete led array data set for each frame
* 4) check first_universe_number, can be found using test sketch (usually is 1, sometimes is zero).
*
*for example, in pixelcontroller i have set the array of 60*8 leds, the universe size set to 30
* and the IP set to 192, 168, 1, 10, and port always remains 6454. At the moment, I can only get
* the frame rate max at 15fps, with 480 leds
*
*so for the sketch, I have ledsPerStrip=60, and I need to set universe size to 30
* number of channels and channel buffer go to 90 automatically (as 3*30). buff2 size can be smaller or biggger
* depending on the total array buffer size requied.
