Problem with DiabloMiner

[PrairieDog]

Have anybody ever received the following error when running DiabloMiner

Code:

Traceback (most recent call last):
  File "./phoenix.py", line 123, in <module>
    miner.start(options)
  File "/home/jacob/miner/phoenix-1.4/Miner.py", line 76, in start
    self.kernel = self.options.makeKernel(KernelInterface(self))
  File "./phoenix.py", line 111, in makeKernel
    kernelModule = imp.load_module(module, file, filename, smt)
  File "kernels/poclbm/__init__.py", line 22, in <module>
    import pyopencl as cl
  File "/usr/lib/pymodules/python2.7/pyopencl/__init__.py", line 3, in <module>
    import pyopencl._cl as _cl
ImportError: libOpenCL.so.1: cannot open shared object file: No such file or directory

I am running ubuntu 11.4 with a Radeon 4650
