I have no programming background, so please bear with me.
When compiling ArduinoSlaveExtruder.pde (downloaded directly from the reprap site) I get the following error:
o: In function `__vector_11':
multiple definition of `__vector_11'/tmp/build54604.tmp/Servo/Servo.cpp.o:/Applications/Arduino.app/Contents/Resources/Java/hardware/libraries/Servo/Servo.cpp:104: first defined here
Please help!
