Exception: clCreateKernel

Hi,
tried my first steps with OpenMM today. Installation on Ubuntu 12.04 went fine, I can run all examples using the reference platform. To fully use all four cores of my machine, I installed the AMD OpenCL SDK. As a quick test, I ran mandelbulbGPU:
OpenCL Platform 0: Advanced Micro Devices, Inc.
OpenCL Device 0: Type = TYPE_CPU
OpenCL Device 0: Name = Intel(R) Core(TM) i5-2400 CPU @ 3.10GHz
OpenCL Device 0: Compute units = 4
OpenCL Device 0: Max. work group size = 1024
Now, if I try to run the OpenMM examples again, I get errors:
>python testInstallation.py
There are 2 Platforms available:
1 Reference - Successfully computed forces
2 OpenCL - Error computing forces
>python simulateAmber.py
Traceback (most recent call last):
File "simulateAmber.py", line 12, in <module>
simulation.minimizeEnergy()
File "/usr/local/lib/python2.7/dist-packages/simtk/openmm/app/simulation.py", line 89, in minimizeEnergy
mm.LocalEnergyMinimizer.minimize(self.context, tolerance, maxIterations)
File "/usr/local/lib/python2.7/dist-packages/simtk/openmm/openmm.py", line 9420, in minimize
return _openmm.LocalEnergyMinimizer_minimize(*args)
Exception: clCreateKernel
What am I missing?
Thanks
Carl
