Problem in FM stereo example

GNU Radio

HI all,
I run the FM stereo example with Ubuntu 8.04 and gnuradio 3.1.3
but now I try to run gnu on fedora 10 with gnuradio 3.2
I got the error like

File “radiogui.py”, line 31, in
from gnuradio import blks
ImportError: cannot import name blks

I copy the FM stereo file in gnu directory still
it give me same error
please If you have any idea guide me

thanks and regards
