Compile - Error (10481): VHDL Use Clause error at auk_ddr_controller.vhd(35):

I am seeing the same problem. I just downloaded Quatrus II 9.0 and tried to build nios2eds\examples\verilog\niosII_cycloneII_2c35\low_cost. I got exactly the same error. I tried renaming the nios2eds\examples\verilog\niosII_cycloneII_2c35\low_cost\db directory and no change.
