Odroid N2 & Airspy - Now running!

Any ideas how to update to 3.7.1 on the N2 ?
I followed @abcd567 previous recs at:
https://github.com/jprochazka/adsb-receiver/issues/471 and changed the version to 3.7.1. That did not seem to do much for the adsb-receiver. Apparently even the compiling was done on version 3.6.3. Do I have to download and compile separately outside of the adsb-receiver install script?

Should I use: https://discussions.flightaware.com/t/dump978-add-on-installation-procedures/49377/17 ?
