Well, after some digging, I'm overlooking the definitions in the file <code> pins_arduino.h</code>.
I could not figure out how to include this, as it's got an <code>ifndef</code> that prevents it from redefining, so I just pasted this block from there at the top of the main sketch:
<code>// CANBus Triple Rev F
#define BOOT_LED 13
#define BT_SLEEP 8
#define CAN1INT 0
#define CAN1INT_D 3
#define CAN1SELECT 9
#define CAN1RESET 4
#define CAN2INT 1
#define CAN2INT_D 2
#define CAN2SELECT 10
#define CAN2RESET 12
#define CAN3INT 4
#define CAN3INT_D 7
#define CAN3SELECT 5
#define CAN3RESET 11
</code>
Probably not the "right" way to do it, but I shouldn't have to screw around like this to get it to compile out-of-the-box.
