And below you seem to have more permissions problems.   If using ports,
that should set things up right, but it's tricky.  The pkgsrc entry
(NetBSD) may be helpful, perhaps more to the port maintainer.

Read the man page for su: https://man.freebsd.org/cgi/man.cgi?query=su

Use -m.  Then use env to adjust the environment, so that PATH is the
system default.

So what happens after you fixed your permissions problems?

How did you install nut?
