That doesn't remove unwanted dependencies, which is what the question
was about.

Try ports-mgmt/pkg_cutleaves or, if  you have portmanager installed
look at the -slid option.

Another important tool is portsclean (installed with portupgrade),
which cleans-out obsolete distfiles, packages, and build directories.

Also look at the options in /etc/defaults/periodic.conf
and /etc/defaults/rc.conf which contain some useful scripts for
automatically deleting things.
