Thanks for your suggestion. I was able to fix it by copying the libOpenCL.so
provided by the ati stream sdk to /usr/lib.
However, running the benchmark-all.py. I get the following errors about a
"double" type not enabled. It looks to me like everything is working
otherwise, including the other tests.
