[Alaelddin Fuad Yousif Mohammed]

Hi All
I am tried to run bbn802.11 , but I faced the following error,

address@hidden:/sdr/douggeiger/src/examples# ./bbn_80211b_rx.py
Traceback (most recent call last):
  File "./bbn_80211b_rx.py", line 37, in <module>
    from bbn_80211b_pkt import *
  File "/sdr/douggeiger/src/examples/bbn_80211b_pkt.py", line 32, in <module>
    from bbn_80211b import *
  File "/sdr/douggeiger/src/examples/bbn_80211b.py", line 46, in <module>
    class bbn_80211b_mod(gr.hier_block):
AttributeError: 'module' object has no attribute 'hier_block'

I am using ubuntu 8.04,USRP1, Gnuradio 3.2.2 which work properly
 I checked old discussion , but I couldn't find the solution.
any suggestion please
