The FETCH_CMD variable set in mk/bsd.pkg.mk should be what you're
looking for.  You can set it /etc/mk.conf like

  .ifdef BSD_PKG_MK
  FETCH_CMD?=	${LOCALBASE}/bin/ncftp3
  .endif

The problem is that if bsd.pkg.mk finds a truncated file after ftp
fails, bsd.pkg.mk regards the file as ``broken'', and tries to fetch
it from the beginning.  It can't recognize if the truncated file is
simply truncated or not so far.  This may be done better way.
