Did you get the correct arch of package? Also, what operating system? Ubuntu?

The correct arch of package? Im using Archlinux. Maybe im pointing to the wrong 
$PATH?
How can i cant the correct path?

Sorry, I got confused, make sure you download the ATI stream sdk package and 
extract it somewhere. Then run "export ATISTREAMSDKROOT=<location where sdk is 
extracted>" in my case that was /home/james/building/ati-stream-sdk-v2.2-lnx32. 
run that straight before the build command.

I did exactly that. Yet i get the same error:

hmmm. It seems to be looking for an libOpenCL.so which it can't find...

Maybe this:

Set the library path LD_LIBRARY_PATH.
– For 32-bit systems:
export LD_LIBRARY_PATH=$ATISTREAMSDKROOT/lib/x86:$LD_LIBRARY_PATH
– For 64-bit systems:
export LD_LIBRARY_PATH=$ATISTREAMSDKROOT/lib/x86_64:$LD_LIBRARY_PATH

i got the libOpenCL.so in /opt/amdstream/lib/x86_64/ but that command didnt 
seem to work or change anything. I still have the same issue. I'm modifying the 
setup.py file to fit my system.

ive changed this part:

OPENCL_INC_DIRS = []
for path in ('/opt/amdstream/include/CL', \
            '/opt/amdstream/bin/x86_64', \
            '/opt/amdstream/lib/x86_64'):
    if os.path.exists(path):
        OPENCL_INC_DIRS.append(path)
        break

Ok, that needs to be fixed then. Looks like someone else had that problem as 
well:

"I had problems with the build and ld reporting it couldn't find the OpenCL 
library:
/usr/bin/ld: cannot find -lOpenCL
collect2: ld returned 1 exit status
A quick workaround was to create a symblink of libOpenCL.so to /lib64:
sudo ln -s /home/ivc/ati-stream-sdk/lib/x86_64/libOpenCL.so /lib64/"

Great! Seems to have worked properly!

Nothing new appears in list. I tried to run "python -c 'from cpyrit import 
_cpyrit_opencl'"

But that gave me:
[niclas@handgranat ~]$ python2 -c 'from cpyrit import _cpyrit_opencl'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: /usr/lib/python2.7/site-packages/cpyrit/_cpyrit_opencl.so: 
undefined symbol: SHA1_Update

Meaning that the installation wasnt that proper afterall - Yet no errors where 
reported during build/install. Now how does this compute? Im gonna try with the 
svn version also.
