This is often a symptom of multiple partially corrupt installations.

To recover, find all places where you may have installed GNU Radio and
remove all relevant files, then rebuild and install.


  $ sudo rm /usr/local/lib/libgnuradio*
  $ sudo rm /usr/local/lib/libusrp*
  $ sudo rm -fr /usr/local/lib/python2.4/site-packages/gnuradio
  $ sudo rm -fr /usr/local/lib/python2.4/site-packages/usrp*
