You are linking against WPILib that is expecting FPGA version 2009 revision 0.1.10 (it had GUID 0x0BA6BBDC5CE760BA2A9A95D92CEA342A, which you can see in the missing symbols). That means REALLY old. That's not even the final image from last year. In fact it was added to WPILib in September 2008. That means you are probably using the DVD distribution release from LAST year. Please install the 2010 C++ Update 4.0 from here: http://www.usfirst.org/frccontrolsystem
