build without X11 support, for use on X11-less servers. Some
dependencies had to be turned off -- until those ports are fixed
to support the NO_X knob as well.
I did not go as far as creating a slave port
(ImageMagick-nox11). (BTW, may be we want a new category --
no-x11 -- for the slave ports of the stuff that's available in
both -- x11 and nox11 -- flavors?)
Nothing should change for the regular (non-NO_X) case -- hence
PORTREVISION not touched.
