Enabling the opencl USE flag in gdal-1.10.1 results in its build failing in configure phase with the error: checking for OpenCL support... checking CL/opencl.h usability... yes checking CL/opencl.h presence... yes checking for CL/opencl.h... yes checking for clGetPlatformIDs in -lOpenCL... no configure: error: --with-opencl requested, but libraries not found! Reproducible: Didn't try Steps to Reproduce: 1. Enable the "opencl" USE flag 2. Try to remerge gdal-1.10.1 Actual Results: Build failure. Expected Results: Any additional required OpenCL libraries should be pulled into the dependency tree. I already have Mesa 10.0.4 with the opencl USE flag installed.

Aha, looks like I found the reason why. The file /usr/lib64/libOpenCL.so exists, but it's pointing to "OpenCL/vendors/amd/libOpenCL.so.1", which doesn't exist. Running `eselect opencl set 1` (of 1, there are no other providers) makes it work (pointing to "OpenCL/vendors/mesa/libOpenCL.so.1"). On this machine I had fglrx installed, then unmerged it to use the radeon driver, so maybe that's related to why there was nothing selected in eselect opencl?
Version is not in tree anymore. Amy
