You need to set PYTHONPATH to reflect the prefix you used during
configuration (default /usr/local).  What --prefix did you use?

Did you build from  /usr/Nett/users/fass/gnuradio or did you install
into there?

Are you running on a 64-bit machine?  If so your python path needs to
contain lib64, not lib.

If you type this command, do you get similar output?

    $ ls -lR $PYTHONPATH/gnuradio/gr


    /usr/local/lib/python2.5/site-packages/gnuradio/gr:
