  Sorry for the delay. I was at C++Now last week.
You need to add the path to clblas.jam to $BOOST_BUILD_PATH
somehow. I know that this is a problem, but I don't
have a good solution. It might be possible for me to
make `using` lazy somehow, but the resulting non-deterministic
initialization order is likely to cause surprises.
