Pyopencl dependence on opencl-icd (and the lack of providing packages) makes it tricky to install

[Niall Murphy]

Goal: install python-pyopencl on Ubuntu 13.10 using the AMD APP SDK 2.9 drivers
http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/
 for CPU emulation on a system with an Intel integrated video card not supported by Intel's drivers.

Steps:
Download and install AMD APP SDK 2.9
Install the ocl-icd-opencl-dev.
Reboot the machine then install python-pyopencl.

Result:
py-opencl works, but on on reboot I cannot log into Unity due to openGL issues with compiz.

Cause:
python-pyopencl depends on opencl-icd.
In my repositories this is only provided by various nvidia-319-updates packages and beignet.
The nvidia packages are selected by apt and install but conflict with, and remove ocl-icd-opencl-dev.
I do not have nvidia hardware.

Fix:
I can install beignet which provides opencl-icd and then install python-pyopencl and use it with ocl-icd-opencl-dev (ignoring beignet as a platform).

Suggestion:
I am unfamiliar with the technical details of icds but:
Should/could ocl-icd-opencl-dev also provide opencl-icd?
Should/could python-pyopencl depend on either ocl-icd-opencl-dev or opencl-icd?
Should apt detect that I dont have Nvidia hardware and install an AMD or Intel driver (beignet) instead?

Status changed to 'Confirmed' because the bug affects multiple users.

I've been having trouble with this as well. Managed to break both ubuntu on my desktop and laptop by accidentally installing the nvidia stuff (that'll teach me to gloss over apt-get "to be installed" lists). Managed to work around it by simply building pyopencl fram source, everything seems to work so far.
