Try replacing DESTDIR="${D}" with install_path="${D}"/usr perhaps?
That's just a guess from examining
http://code.google.com/p/gpuocelot/source/browse/trunk/ocelot/SConscript
.

And for your first problem with CXXFLAGS, try

export OCELOT_CONFIG_FLAGS="${CXXFLAGS}"

That probably still leaves LDFLAGS which should probably be set in LINKFLAGS.
