[Discuss-gnuradio] error on running usrp2_version of 80211

[maher manai]

when i run the 80211b.test.py it appears an error wich is
address@hidden examples]# ./bbn_80211b.test.py
bash: ./bbn_80211b.test.py: Aucun fichier ou dossier de ce type
address@hidden examples]# ./bbn_80211b_test.py
Traceback (most recent call last):
  File "./bbn_80211b_test.py", line 35, in <module>
    from bbn_80211b_pkt import *
  File "/home/maher/usrp2_version/gr-bbn/src/examples/bbn_80211b_pkt.py", line 32, in <module>
    from gnuradio import bbn
ImportError: cannot import name bbn

i ask if it's a problem of gcc or another problem
