Your suggestions are helpful.

My interpretation of the web page was that I was to create another
set of system variables, like PYTHONPATH etc.
Your suggestions did get gnuradio 3.7 working again on my MacBook Pro (late 
2013) running Mojave 10.14.6.
(Initially I thought I had 3.8 running, but I still need to update the links to 
gnuradio 3.8).

I’ll keep at installing 3.8



Again I do have gnuradio 3.8 working reasonable well on my Ubuntu computer, but 
of my programs yet running.

I’m trying to use gr_modtool to get a new gr3.8 module compiled with make,
then I’ll inch through comparisons of the old cmake format and new.

It would be convenient to have a very very simple example of 
both python and c++ programs that were already able to be built, so that
we don’t have to step through the gr-modtool example web page updated 
squareff.cc etc.
