> Actually, '-f' DOES mean force. But, in this context "force" just means to
force deletion even though there are still dependent ports/packages
installed. This is documented in the pkg-delete(8) man page (in two places):
     "If the set of packages to be deleted would leave installed packages
     unfulfilled dependencies, pkg delete will add the packages with
     unfulfilled dependencies to the list of packages to be deleted, unless
     forced to proceed without deleting any other packages by the -f
     "-f, --force
                Forces packages to be removed despite leaving unresolved
                dependencies.  In combination with the -a or --all flag,
                causes pkg(8) to be removed as well as all other packages."

Unfortunately, reading the man pages is usually the last resort. (Common
expression is "When all else fails, read the instructions".)
