Why did nvidia-cuda-toolkit tried to install nvidia-opencl-dev when you had ocl-icd-libopencl1 installed?
From what I can tell, because of the missing 'conflicts'.
$ apt-cache show nvidia-cuda-toolkit Package: nvidia-cuda-toolkit Version: 5.5.22-4 Installed-Size: 44180 Maintainer: Debian NVIDIA Maintainers <pkg-nvidia-de...@lists.alioth.debian.org> Architecture: amd64 Depends: nvidia-profiler (= 5.5.22-4), nvidia-cuda-dev (= 5.5.22-4), nvidia-opencl-dev (= 5.5.22-4) | opencl-dev, gcc, g++, libc6 (>= 2.3.4), libgcc1 (>= 1:4.1.1), libnvvm2 (>= 5.5), libstdc++6 (>= 4.1.1) ocl-icd-opencl-dev depends on ocl-icd-libopencl1, and ocl-icd-libopencl1 conflicts with libopencl1, preventing other packages with libOpenCL.so from being installed.
But nvidia-opencl-dev conflicts with opencl-dev, and ocl-icd-liopencl1 conflicts with libopencl1.
There is no explicit conflict between each other.
Can you provide what you were doing?
I was simply trying to reproduce the similar problem that occurs in Ubuntu, see LP: #1311975, LP: #1325526 and LP: #1341072.
So I did: apt-get install ocl-icd-libopencl1 followed by: apt-get install nvidia-cuda-toolkit
I have situation similar to described by you (ocl-icd-opencl-dev and ocl-icd-libopencl1 and nvidia-cuda-toolkit) and did not have any troubles - I even prepare and test PyCUDA and PyOpenCL packages on such a setup.
If you install ocl-icd-opencl-dev *after* nvidia-cuda-toolkit, the problem does not occur.
