CUDA samples compilation error.

I have tried a compile on one of the basic NVIDIA CUDA samples and am getting the following compile error:

nvcc fatal : Unsupported gpu architecture ‘compute_21’
make: *** [src/matrixMul.o] Error 255

The platform is Ubuntu12.10 - Linux, and the compile is done via the standard Nsight eclipse edition IDE. The CUDA hardware is GeForce 210 which supports CUDA compute level 2.1

Has anyone encountered this error, and does anyone know a work-around?
