Hi Marcus,

    Thanks.   That was very helpful.   If there was an instruction to run the 
setup_env.sh script I missed it.    I was flying a bit blind there, because the 
link to the PyBOMBS web page from the GNUradio TWiki---i.e.,

URL: http://gnuradio.org/pybombs    from

URL: http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGRFromSource 

leads to a non-existent page.

    When I ran the setup_env.sh script, things started to work.  That's a good 
thing!    I am concerned, however, that I have a mixed installation.   What is 
my best move?   "rm"-ing all of the PyBOMBS stuff or just leaving well enough 
alone (I realize that this question may not have a "closed form" answer, but 
advice would appreciated nonetheless).

Best regards,
Dan
