I have a problem with ofdm system.

Each time I run benchmark_ofdm_rx.py I get;

Traceback (most recent call last):
  File "benchmark_ofdm_rx.py", line 210, in <module>
  File "benchmark_ofdm_rx.py", line 199, in main
    tb = my_top_block(rx_callback, options)

line 946, in connect
    return _gnuradio_swig_py_runtime.gr_hier_block2_sptr_connect(*args)
ValueError: port number 1 exceeds max of 0

I use  realese number 7324 and  kubuntu 7.04
