As far as I know, every occurence of this has been a result of partial
stale installations of GNU Radio, or multiple overlapping
installations.
My suggestions:
$ rm -fr /usr/local/lib/python2.4/site-packages/gnuradio
$ rm -fr /usr/local/lib/python2.4/site-packages/usrp*
$ rm /usr/local/lib/libgnuradio*
$ rm /usr/local/lib/libusrp*
Then start with a fresh check out from svn into AN EMPTY DIRECTORY, or
unpack the latest tarball into AN EMPTY DIRECTORY.
See http://gnuradio.org/trac/wiki for directions on getting the code.
Also, check your PYTHONPATH and make sure that it's reasonable.
Most folks have something like:
address@hidden mail]$ echo $PYTHONPATH
/usr/local/lib/python2.4/site-packages
