Re: TrueNAS usage

I'm not Denis, but I might make a suggestion:

your path of least resistance is probably a Dar static build.  You could
use the files from Denis's site at
https://dar.edrusb.org/dar.linux.free.fr/Releases/Dar_static/x86_64_GNU_Linux/
or copy /usr/bin/dar_static from a Debian system that has dar-static
installed.

My guess is that TrueNAS doesn't include the development files (headers,
etc) for those libraries.
