You need to install clblas or clblast to have a blas for opencl. Without that, it is missing many operation.
Note, in Theano, we are missing many/some operation in OpenCL. We don'T have time to work in the short term on that. So if your goal is to use opencl with Theano, you will probably need to help us convert some cuda code to our code that support cuda and opencl.
