Part of the problem from your dump is that it is appears you are trying to mine on an HD4600 series... To my knowledge only the HD4670 and 4800's support OpenCl, and barely at that. See if you can find a more modern card to try, you will get better OpenCL support and better (if diminishing) returns.
He has a 4670, if you read the dump. The HD4000 series introduces OpenCL support. Although I have not tried a 4000 series, the hardware wiki suggests they work, at least, worked with the older miner versions used to test them.
They all support OpenCL 1.0. The integrated 4xxx series don't because they are actually RV620. Just like the 3xxx integrated are actually RV610. I can't imagine any devs working on miners caring about compatibility with these cards though.
Ah, I didn't manage to pick out it was a 4670 from the dump. I only spotted the series...
