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
