Cannot connect Wifly Shield to Arduino Uno

I don't know what tutorial you are using, but I downloaded the WiFly_Terminal.pde code from the link you posted.

Those erros appear to be caused by a conflict between pins_arduino.h and WiFly_Terminal.

WiFly_Terminal.pde

// Arduino SPI pins
#define CS         10
#define MOSI       11
#define MISO       12
#define SCK        13

Those defines do bad things to these in pins_arduino.h

const static uint8_t MOSI = 11;
const static uint8_t MISO = 12;
const static uint8_t SCK = 13;
