This happens because neither the locate nor the updatedb command is not 
installed to your system (they are in one package)
The "locate" is not connected to gnuradio at all, but rather a useful 
tool in linux systems. If you read the link above, and I'm sure you did, 
it is clear to you that the "updatedb" makes a hash database of your 
files in your system where are they etc, and the command "locate" uses 
the database made by the "updatedb" to find patterns in filenames. So 
the command
"$> sudo updatedb" creates or refreshes the database (you need to run it 
with admin privileges)
and the command "$>locate gnuradio" finds all filenames which contains 
the term gnuradio.
I'm pretty sure that you know what a pipe is and the "cleared screen 
with (END) in the upper left corner" is made by the program less, 
because it did not receive anything from the command "locate gnuradio" 
so it displays an empty string.

So this suggestion was just only to help you find your gnuradio files on 
your system, it is not connected to gnuradio by any means.
