In Sid, the situation is as follows:

$ apt-file search libOpenCL.so
amd-libopencl1: /usr/lib/x86_64-linux-gnu/libOpenCL.so.1
amd-opencl-dev: /usr/lib/x86_64-linux-gnu/libOpenCL.so
nvidia-libopencl1: /usr/lib/x86_64-linux-gnu/libOpenCL.so.1
nvidia-libopencl1: /usr/lib/x86_64-linux-gnu/libOpenCL.so.1.0.0
nvidia-opencl-dev: /usr/lib/x86_64-linux-gnu/libOpenCL.so
ocl-icd-libopencl1: /usr/lib/x86_64-linux-gnu/libOpenCL.so
ocl-icd-libopencl1: /usr/lib/x86_64-linux-gnu/libOpenCL.so.1
ocl-icd-libopencl1: /usr/lib/x86_64-linux-gnu/libOpenCL.so.1.0.0
ocl-icd-libopencl1: /usr/share/man/man7/libOpenCL.so.7.gz

Packages providing virtual package libopencl1 [1]:
amd-libopencl1
nvidia-libopencl1
ocl-icd-libopencl1

Packages providing virtual package opencl-dev [2]:
amd-opencl-dev
nvidia-opencl-dev
ocl-icd-opencl-dev

So OpenCL development packages provide opencl-dev and OpenCL library 
packages provide libopencl1.

If ocl-icd-libopencl1 is going to continue shipping libOpenCL.so, then I 
think the conflicts/replaces simply need to be updated to amd-opencl-dev 
and nvidia-opencl-dev (instead of amd-app and nvidia-libopencl1-dev), as 
per my updated patch (attached).

If ocl-icd-libopencl1 is going to stop shipping libOpenCL.so, then it 
only needs to conflicts/replaces on libopencl1 and the remaining 
conflicts/replaces (amd-app and nvidia-libopencl1-dev) can be dropped.  
Package ocl-icd-opencl-dev can then ship libOpenCL.so and no further 
changes need to be made as it already conflicts/replaces on opencl-dev.

Can we agree that the fix to bug #755513 lies in ocl-icd?  I'd like to 
mark nvidia-cuda-toolkit as no longer being affected so it can go back 
into testing.
