Bug#755513: nvidia-opencl-dev: binary conflict with ocl-icd-libopencl1

Why did nvidia-cuda-toolkit tried to install nvidia-opencl-dev
when you had ocl-icd-libopencl1 installed?
$ apt-cache show nvidia-cuda-toolkit
Package: nvidia-cuda-toolkit
Version: 5.5.22-4
Installed-Size: 44180
Maintainer: Debian NVIDIA Maintainers
<pkg-nvidia-devel at 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.

Can you provide what you were doing?
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.

Best regards.
