[Discuss-gnuradio] Issue with swig in packet_headerparser block

Hi,

I am trying to create packet_headerparser block. The purpose is to first  duplicate the block and then modify it (mostly I would like to modify the dict part). I followed the the instruction in howto tutorial but I got the error below when I tried to run the  qa_packet_headerparser_b.py. I am not sure what I did wrong but I was able to duplicate demux block and make it work fine. Any hint on this is grealty appreciated.

Traceback (most recent call last):

  File "/home/dev/Gnuradio_Prjs/parser/gr-sperry/python/qa_packet_headerparser_b.py", line 28, in <module>

    import sperry.sperry_swig as sperry
