Hi,
Followed the steps exactly as described there. Here's what I get when I try to run poclbm.exe:
Traceback (most recent call last):
File "poclbm.py", line 5, in
File "pyopencl\__init__.pyc", line 3, in
File "pyopencl\_cl.pyc", line 12, in
File "pyopencl\_cl.pyc", line 10, in __load
ImportError: DLL load failed: The specified module could not be found.
This was also mentioned in
http://bitcointalk.org/index.php?topic=1334.280 (with no definitive fix offered). Since you invited feedback on this guide... here it is

The steps must be somewhat incomplete.
I'm running Win7 64-bit and have an HD5770. I have the latest driver but no ATI Stream SDK (but then the guide didn't ask for it... do I need it?)
