Conda seems to ignore 'osx_pocl_opencl'

Job #62866 failed for c928ccd7:

In the job log, I see the following packages installed together:

osx-pocl-opencl           1                             0    conda-forge

pyopencl                  2018.2           py36h81a3be6_1    conda-forge

(Especially: not the pocl variant of pyopencl)

According to my reading of the conda docs, this shouldn't happen. @isuruf, any idea what might be wrong?
