nice, something real to test it on. :)

After ./configure, in include/Make/Platform.make what do these settings say?

OCLINCPATH          = 
OCLLIBPATH          = 
OCLLIB              = 
USE_OPENCL          = 

If it is set ok there then we need to do something more than just set
in r.sun's Makefile.

re. the libs, see also the "needed?" comment in the Makefile. Maybe
one of those need to be enabled.
