I get these errors:-

core.a(main.cpp.o): In function `main':
/Users/ricktwyman/Downloads/Arduino-2.app/Contents/Resources/Java/hardware/arduino/cores/arduino/main.cpp:5: undefined reference to `setup'
/Users/ricktwyman/Downloads/Arduino-2.app/Contents/Resources/Java/hardware/arduino/cores/arduino ...

"Show verbose output during compilation"
