[SOLVED] Errors when executing px4 on the Pi3 with Navio2

I successfully completed a native build of the 1.7.3 release on the Raspberry Pi 3 by following the instructions here and here

However, I get these errors when I run it. Are there extra steps missing in the instructions?

Never mind. The /boot/config.txt actually had the dtoverlay=navio-rgb declared in two places and I missed to comment out one. It works now.
