Depending on the OpenCL implementation the compiled binaries may be cached,
by the system, to minimize the overhead of recompiling the .cl sources upon
program load. But if you change the source files it should recompile the
code again next time you launch the program.

Make sure you are running the right mged and rt binaries. It sounds like
maybe you aren't running the version you modified.
