Well… that was a journey… I finally stumbled upon an older post that had the final key. Although I was concerned that is was old data that had been since replaced with new methods… may even still be that way??
But alas… https://github.com/blynkkk/blynk-library/blob/master/linux/README.md had the final pieces.
I added these lines (into terminal on my RPi) onto my past efforts:
git clone https://github.com/blynkkk/blynk-library.git
cd blynk-library/linux
make clean all target=raspberry
And now it even connects to my Local Server with the ‘proper’ command:
sudo ./blynk --server=10.10.3.204 --port=8442 --token=xxxxxxx
So I guess some of the DOCs aren’t completely wrong… just missing much info! 
or may include unnecessary info… Is installing Node & ONOFF even required steps due too the inclusion of wiringPi?
Now to figure out how to create and edit sketches, properly, on the RPi…
