I guess, the reason is that you do not have python module "audio" installed. At
Python prompt, what does
>> from gnuradio import audio
return? Does it show any error?
The dialtone example, generates the dialtone and sends out to your soundcard, so
you need the OSS driver to listen to it.

If PYTHONPATH is setup, there is no need for any special directory structure.
