DriverStationEnhancedIO compile error

[oddjob]

I copied this out of WPI_Robotics_Library_Users_Guide.pdf and put it in the constructor:

    DriverStationEnhancedIO &dseio = DriverStation.GetInstance().GetEnhancedIO();

Here is the compile error:

C:/WindRiver/workspace/BuiltinDefaultCode/BuiltinDefaultCode.cpp: In constructor `BuiltinDefaultCode::BuiltinDefaultCode()':
C:/WindRiver/workspace/BuiltinDefaultCode/BuiltinDefaultCode.cpp:99: error: expected primary-expression before '.' token
C:/WindRiver/vxworks-6.3/target/h/WPILib/DriverStationEnhancedIO.h:127: error: `virtual DriverStationEnhancedIO::~DriverStationEnhancedIO()' is private
C:/WindRiver/workspace/BuiltinDefaultCode/BuiltinDefaultCode.cpp:99: error: within this context

C:\WindRiver\vxworks-6.3\host\x86-win32\bin\make.exe: *** [BuiltinDefaultCode_partialImage/Debug/Objects/BuiltinDefaultCode/BuiltinDefaultCode.o] Error 1

Is the pdf file wrong, or I did something wrong?
