cycles renderer gives me a drop down menu with two options supported & experimental but when i choose experimental there no option to select, i.e. opencl gpu/cpu.....

the compilation follows the instructions by wiki, i compiled this using scons,
this is my user-config.py file,

Code:

BF_PYTHON_ABI_FLAGS = 'm'  # Most common for linux distros #ffmpeg WITH_BF_FFMPEG = True # FFT #WITH_BF_FFTW3 = True   # Cycles WITH_BF_CYCLES = True WITH_BF_OIIO = True WITH_BF_STATICOIIO = True BF_OIIO = '/home/npm1/Compilations/Blender/linux64/oiio' BF_OIIO_INC = '${BF_OIIO}/include' BF_OIIO_LIB_STATIC = '${BF_OIIO_LIBPATH}/libOpenImageIO.a '#${BF_OPENEXR}/lib/libIlmImf.a BF_OIIO_LIBPATH = '${BF_OIIO}/lib' WITH_BF_BOOST = True WITH_BF_STATICBOOST = True BF_BOOST = '/home/npm1/Compilations/Blender/linux64/boost' BF_BOOST_INC = '${BF_BOOST}/include' BF_BOOST_LIB_STATIC = '${BF_BOOST_LIBPATH}/libboost_filesystem.a ${BF_BOOST_LIBPATH}/libboost_date_time.a ${BF_BOOST_LIBPATH}/libboost_regex.a ${BF_BOOST_LIBPATH}/libboost_system.a ${BF_BOOST_LIBPATH}/libboost_thread.a' BF_BOOST_LIBPATH = '${BF_BOOST}/lib'

how can i resolve this
