Hi, I am using a MacBook Pro from 2011 and I am trying to work with GNU  
RADIO (nightmare).

I installed all the software two weeks ago and have been working with  
it  
during last week. Nevertheless, today it seems not to work anymore.  
When I  
try to open it typing in the terminal “gnuradio-companion” I get the  
following message:

“-bash: gnuradio-companion: command not found”

What’s happening? Thanks a lot.
