AFAIK OpenCL should work without OpenGL. But you are probably better off
installing OpenGL in the first place. You need to install the drivers
specific to your graphics hardware. Just installing some Mesa libraries is
not sufficient to get accelerated OpenGL support. You can then test if
OpenGL support is working with the 'glxinfo' command or running some OpenGL
program like 'glxgears'.
