Comment (by kencu):

 MacPorts is powerful, and the admins and devs have chosen to keep more
 options available at the expense of it being slightly more complicated for
 users, especially initially. Homebrew has taken the opposite approach, no
 variants, usually one option for things, and they don't support users
 building their own software, even.

 MacPorts has four xorg-server ports:
 {{{
  % port search xorg-server
 xorg-server @1.20.11_1 (x11, devel)
     The X.org / Xquartz X server.

 xorg-server-1.18 @1.18.4 (x11, devel)
     The X.org / Xquartz X server.

 xorg-server-devel @1.20.99.1_1 (x11, devel)
     The X.org / Xquartz X server.

 xorg-server-legacy @1.20.10_2 (x11, devel)
     The X.org / Xquartz X server.
 }}}

 The primary xorg-server port works for almost all users on newer systems.
 The xorg-server-legacy port works on the older systems where the primary
 port no longer usually will build or work properly. The other two xorg-
 server ports have uses, the 1.18 version on Tiger, and the devel version
 for devs to use to move the envelope down the path for the next update.

 Now ideally when you tried to install xorg-server on a system that is too
 old to support it, it would not tell you it won't build, but try anyway --
 that is kinda confusing -- what it would do is say that that xorg-server
 doesn't work on your system, so MacPorts will be installing xorg-server-
 legacy for you instead. Wouldn't that be great?

 It's not overly hard to write that code into the Portfiles, but nobody who
 is capable of doing that (like me) has bothered to do it, because there
 are just too many other things to do. It would be really great if users
 like you might get to the point where you could add that to MacPorts for
 us.... we'd really appreciate it.
