[Haskell-cafe] Missing symbol when trying to use OpenCLRaw

Can anyone tell me what command line options I need to build a simple example using OpenCLRaw on MacOSX (ghc 6.10.4)? Using "-framework OpenCL" reduces the missing symbols down to just _clGetProgramInfo but I can't see how to eliminate that last one. Has anyone else played with OpenCLRaw? -- Dan
