[Discuss-gnuradio] Using gr-wxgui

[Melody S]

Hi 

I am trying to use the gr-wxgui  but when I run the commands 
%pythonw scopesink.py 
%pythonw fftsink.py
 %pythonw waterfallsink.py 

I get the following errors

Traceback (most recent call last):
  File "scopesink.py", line 23, in ?
    from gnuradio import gr, gru, eng_notation
ImportError: No module named gnuradio


But I already have installed the gnuradio and all the Makefile , 
Makefile.am , Makefile.in have been built, so I have the gnuradio module but it says that I don't. 

Would anyone please help me with this.
Thanks
