Teensy
Teensy 3.1
Teensyduino 1.20 in combination with Arduino 1.0.6 is able to compile Arduino code. Do not use Ardunio 1.6.0, it will fail. CrossPack for AVR maybe enables OSX to compile C-code with command line for Teensy 3.1 (not tested)

Compile
- Start Ardunio_Teensy
- Select: Tools -> Board -> Teensy 3.1
- Select: Tools -> CPU-Speed -> 72 MHz
- Select: Tools -> USB-Type -> Serial
- Select: File -> Examples -> Teensy -> Tutorial1 -> Blink
- Compile with const int ledPin = 11;
- Connect Teensy 3.1 board to USB port
- LED is blinking (runs default application from factroy)
- Flash board - maybe you have to press the button on the Teensy board and flash again
- Board stops blinking (because ledPin is 11 at Teensy 3.1)
- Now change to ledPin = 13 and flash again to check if led is blinking again
