[David Marceau <uticdmarceau2007@xxxxxxxx>]

status of golang/opencl on ubuntu phone saucy stable nexus 4:
-updated to Golang 1.2 did not fix this error.

Isolating golang out of the equation, I tried to just C++ compile Bolt,
but its cmake project required BOOST_ROOT environment variable.  In
order to have this, I resorted to trying to compile straight from
BOOST.org web site's tar.gz rather than apt getting sources.  What a
headache.  I did not succeed in compiling BOOST with cmake because it
boost.org doesn't use cmake.  OpenCL as shipped from AMDAPP requires cmake.

Recommendation:
-have ubuntu desktop & ubuntu phone install cmake support for
Boost/Bolt/OpenCL along with pre-built binaries
-have opencl support within ubuntu saucy nexus4 and desktop repositories.

Cheers,
David Marceau
