From what I can tell, because of the missing 'conflicts'.

But nvidia-opencl-dev conflicts with opencl-dev, and ocl-icd-liopencl1
conflicts with libopencl1.
There is no explicit conflict between each other.

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
apt-get install nvidia-cuda-toolkit

If you install ocl-icd-opencl-dev *after* nvidia-cuda-toolkit, the
problem does not occur.
