Packages should never install stuff in /usr/bin and /usr/sbin. Ports
should *only* install files in /usr/local/... There are a few ports that
includes options to override base-system files in /usr but these are the
exception.
If you have been upgrading from source from 7.2 then you should also
have a look at the `/usr/src/UPDATING' file; especially at the help
about the 'make delete-old' targets of the source makefiles.
Most of the cruft left behind from old, obsolete stuff can be deleted by
running
# cd /usr/src
# make delete-old
and following the prompts.
