As I said before I don't know if you need to install OpenGL to run OpenCL
on your system or not. At one point I know you could run OpenCL on an
NVIDIA GPU without an X Server (headless), while on an AMD GPU you needed
to run the X Server to get working OpenCL as it was a dependency. I could
look into this, but I don't know if it's worthwhile to spent time on this
feature or not as most people will have both working and in the future we
could make OpenGL a dependency in order to have working texture mapping or
to use some other feature.
Just get OpenGL and OpenCL working. If you are a CentOS user a good place
to ask is probably on the #centos channel at irc.freenode.net:
