Always remember:

FreeBSD places system programs in /bin, /usr/bin etc., while
3rd party programs to to /usr/local/bin; sudo is not part of
FreeBSD, so it's easy to conclude _where_ it has to be located.
(Sidenote: Few ports have options to make them install into
system directories or replace system programs, for example
bash or CUPS, but that is usually not the default.)

Supplied by FreeBSD: su

Additional programs: sudo, super
