As an alternative, are there some C libraries available for NetBSD,

manage the GPIO pins?
NetBSD uses the gpio(4) device to talk to the GPIO pins:
http://man.netbsd.org/gpio.4
So your program opens /dev/gpio and uses ioctl to do things. This
should be relatively straightforward in C (or perhaps in Go).
In support of Benny's claim, in the NetBSD 7 era I managed to figure out
the GPIO basics despite not knowing much of anything about anything.
