So I decided to treat myself for my birthday and upgraded my MacBook Pro to the new 15″ retina.  Very fun.  Migrating over has been mostly trouble free but there were a couple of issues.  I prioritized getting the Teensy and Arduino build environments up and running.  Nothing strenuous but there was a small code change necessary.  Download and install:

• https://github.com/adafruit/Adafruit-GFX-Library [Graphics Library]
• https://github.com/adafruit/Adafruit_SSD1306 [OLED code]

  • Adafruit_SSD1306.cpp:425:26: error: 'TWBR' was not declared in this scope

  • Comment out references to TWBR
• https://github.com/adafruit/Adafruit-WS2801-Library [RGB LED strand]
• http://www.pjrc.com/teensy/td_download.html – This includes the XBee library and other libraries modified for used by the ARM platform

And that was it!  The makefiles needed a little modification to refer to the Arduino / Teensyduino installation but that was it.  Compiling 10 times faster!
