Ok, I've been reinstalling with GIT distro for some time now.  I'm almost 
there.  I'm on Ubuntu 8.04 and I seem to have all the packages, the only things 
left are:

gcell
gr-gcell
gr-audio-jack
gr-audio-osx
gr-audio-portaudio
gr-audio-windows
gr-comedi
gr-video-sdl
gr-qtgui


When I run usrp_fft.py ...

  File "usrp_fft.py", line 24, in <module>
    from gnuradio import usrp
  File "/usr/lib/python2.6/dist-packages/gnuradio/usrp/__init__.py", line 25, 
in <module>
    
  File "/usr/lib/python2.6/dist-packages/gnuradio/usrp/usrp_swig.py", line 6, 
in <module>
ImportError: No module named _usrp_swig

thanks for the help.
Joe
