multi_tone.py is now broken as it requires audio_portaudio and audio_jack 

barossa: {11} ./multi_tone.py -O /dev/audio
Traceback (most recent call last):
  File "./multi_tone.py", line 25, in ?
    from gnuradio import audio_portaudio
ImportError: cannot import name audio_portaudio

Why force users to install all modules in order to run a otherwise very simple 
test application? Jack and portaudio may not even be available for some
