Dropping security@...
The OPTIONS feature stores port preferences and helps a lot with this.
Not all ports are converted yet, but that's just a matter of time. My
only complaint is that when options are added I'm not prompted for my
preference (I just get the default value). I have to go back and
manually "make config" if I don't want the default. If automatic
prompting for new options is added then we will truly have a "set it and
forget it" configuration system. Because I track ports fairly closely
and usually catch new options, this hasn't annoyed me enough to fix it...

You have to tell the ports system you don't want X (put the following in
/etc/make.conf):
WITHOUT_X11= yes
There are also ports (like bittorrent) that install GUIs by default.
You should also tell the ports system you don't want GUIs:
WITHOUT_GUI= yes
Some ports will still need the X libs (like graphviz), but that's not a
huge deal.
