I tried both poclbm and phoenix.py and get similar errors for each

poclbm.py:
Traceback (most recent call last):
  File "poclbm.py", line 24, in
    platforms = cl.get_platforms()
pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error c

phoenix.py:
Traceback (most recent call last):
  File "./phoenix.py", line 123, in
    miner.start(options)
  File "phoenix-1.50/Miner.py", line 75, in start
    self.kernel = self.options.makeKernel(KernelInterface(self))
  File "./phoenix.py", line 112, in makeKernel
    self.kernel = kernelModule.MiningKernel(requester)
  File "kernels/poclbm/__init__.py", line 132, in __init__
    platforms = cl.get_platforms()
pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code
