Turning off X support is only necessary if the system doesn't need X
installed at all. A version with the X support included will work fine
on the console.

In the Makefile. You'll find that the option does two things:
  Makefile:LIB_DEPENDS+=	libvga.so:${PORTSDIR}/graphics/svgalib
makes this port depend on the svgalib port, and
  Makefile:CONFIGURE_ARGS+=	--with-svgalib
sets up to tell configure to use svgalib
