The HardenedBSD packaging environment does not support the ftp protocol.
Currently in stable13 and current, there are 39 skipped ports entries because of luit (xorg, gdm, gnome3 & more...) and 16 entries because of bmake (dict, dictd, inputplug, mk-configure & more).
It's therefore preferable to change the MASTER_SITES for x11/luit and devel/bmake.
