I am using using ubuntu 12.10 i am trying to run OP25 (python version 2.7.3), in GNU Radio Companion v3.6.3-35-g4435082f and i get an error. So I run the traceback command in terminal:

~$ python -m trace --count -C . op25_grc.py

Here is the output with an error:

Imported legacy fsk4

Traceback (most recent call last):

return getattr(self._hb, name)
AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'

I really really want to get OP25 running but have not been able to figure out what is the solution to this error (AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback')
.  it'll take me ages to figure out how to debug in python. some threads have said its because gnuradio is an older version but in my case it is not.  i am wondering if the question is too amateur or something because nobody is lending assistance.  

Any help will be so very much appreciated.  Thanks.
