i can't really tell what you are doing with all this. You are on some 
debian-based system and installing from apt, then checking out the development 
version from svn but not using it.

The point seems to be that in your step 7 you symlink the opencl-library, but 
in point 6 setup.py already complained about missing libopencl ("/usr/bin/ld: 
cannot find -lOpenCL"). Try rebuilding and installing the opencl-module now 
that libopencl can be found.

"svn: '.' is not a working copy" is just a warning that the directory you are 
building from has not subversion-files in it. This can be ignored if you are 
installing from packed tarballs.

Ok! It's works.

But I think the controller (ATI Technologies Inc RV730XT [Radeon HD 4670]) do 
not performance well. :(

you may try the calpp-plugin which is in 0.4.0-dev - it gives better 
performance on ati cards
