I really should start writing answers longer than just one sentence...

Or in code. :)

I'm guessing the problem here is the missing link from libOpenCL.so to libOpenCL.so.1 . The newer BOINC version is smarter and checks both file names. If you remember you are the one who got David to make that change.

Ah all right, but then a next time do explain that to the user as well. ;-)
And no, I don't remember that I did that, but then I don't remember half of he options and bug fixes I managed to get into BOINC. Old age and memory. Sigh.

NVIDIA drivers should come with both CUDA and OpenCL components.

Yes well, that's the thing. I don't think we can easily say the OpenCL component is included in the drivers from Nvidia, for isn't that a separate package on some distros, called opencl-nvidia? Or that it's needed to install an SDK or CUDA Toolkit?

I know that under Windows you just have to install the drivers by and from Nvidia and be done, but under Linux it really depends on the distro if that is supported and that you don't need to jump through additional hoops to get things working.
