### [Wed Dec 12 12:47:17 JST 2012 : pho]
### GEGL tries to use OpenCL in a really weird way. It has (and
### installs!) a local copy of OpenCL headers and then tries to find
### implementation by dlopen'ing "libOpenCL.so". The problem is that
### it fails to compile on Darwin < 10 by trying to include
### non-existent native OpenCL headers too, which is in fact only
### optional.
