Oh ok I didn't realize it was complaining about OpenCL since it was running on CPU only mode. I will fix it when I get to enable the GPU. For the 3000 Gkeys I am working on it 
It's a tribute to the unified generators (earlier we had different generators for CPU and GPU, now the binary supports both), it needs to dynamically link against a OpenCL library - but you can install a dummy one:

Most linux distributions have that as a package.
