I am running ubuntu 14.04 64 bit and nvidia drivers 331.38 and had the same problem of OpenCL not being available in Darktable.

This got fixed for me by a solution proposed to fix another OpenCL issue here:
http://askubuntu.com/questions/449507/nvidia-libopencl1-331-has-to-be-removed-before-installing-wine?rq=1

What I did was:

sudo apt-get install nvidia-cuda-toolkit

and then

sudo apt-get install ocl-icd-opencl-dev

After a reboot, Darktable's "activate OpenCL support" is not greyed out anymore and seems to work like it should.
