PyCUDA and PyOpenCL installation on Ubuntu 12.04 with NVIDIA graphics

First install newest NVIDIA driver. 'nvidia-experimental-310' from ppa was good for my laptop's GT220M. For desktop's GTX550Ti I needed to install driver manualy from nvidia.com. Next step is to download CUDA pack from developer.nvidia.com, and latest PyCUDA and PyOpenCL from  https://pypi.python.org/pypi/pycuda and https://pypi.python.org/pypi/pyopencl respectively.
