That is horribly inefficient because it forks a separate
grep process for every single file under /usr/ports.
Also it will print a lot of false positive, because the
ports tree contains several files and scripts that call
adduser.

That won't work, because pkg_info only reports information
about packages that you have installed.
One way to find which ports provide a certain file is to
use the "porgle" search engine:
http://www.secnetix.de/tools/porgle/?w=p&q=adduser
However, there is an adduser command in /usr/sbin which is
part of the FreeBSD base system. If some script complains
about that command being missing, you should invstigate
whether you do have that command in /usr/sbin.
It's unlikely that a port requires a different command with
the same name without having a dependency on the port that
provides that command.
Best regards
