Hi Alysson,
I've attach a modified version of your code that works with GNU Radio
3.1 and 3.2. I suggest that you try using the 3.2 release.
If you happen to be running Ubuntu 9.04 (Jaunty) you can download
prebuilt binaries:
http://gnuradio.org/trac/wiki/DebianPackages
Otherwise, please download the source and build it:

There are many examples, see
