Ardunio DUE Using 1.6.5 Cannot Load Servo Library!

Hello, I am running on the Ardunio 1.6.5 and whenever I do #include <Servo.h> it gives this message:

NewChassis.h:1:19: fatal error: Servo.h: No such file or directory
 #include <Servo.h>
compilation terminated.
Error compiling.

I have tried literally everything I can think of. Any help/ideas would be GREATLY appreciated.

What happens when you try it with the Arduino Uno selected in Tools > Board?
