No. +quartz means use native Mac OS X graphics, not any X11 implementation.


 2) How does http://xquartz.macosforge.org/ relate to the quartz-wm port?
 Specifically,
port install quartz-wm + quartz-wm --version produces version 1.3.1
 while the
XQuartz site shows version 2.7.4 + the XQuartz site implies quartz-wm
 is part of
it's code (The quartz-wm window manager included with the XQuartz
 distribution...)


The individual ports comprising X11 in MacPorts are the same as the
distribution at http://xquartz.macosforge.org, aside from differing paths.
They also have the same maintainer. But individual components (xorg-server,
quartz-wm, xterm, etc.) have their own version numbers, which are reflected
in the port versions; you would have to read the release notes in the
XQuartz distribution to see these for the dmg distribution.

3) Last. Seems like XQuartz is more up to date code than X11. Is there any
 situation
where +x11 variant is preferred over +quartz?


This question is somewhat incorrect given that +quartz does not refer to an
X11 distribution at all. But there are a number of Gtk+-based programs
which, while they can build using the native or X11 versions of the
toolkit, don't behave correctly with native graphics. (One example is that
xchat using the native toolkit doesn't scroll chat windows properly.)

Not in all ports. Some ports, libraries in particular, can often be installed 
with support for both X11 and Quartz graphics.

 someone clarify the differences.
 
 1) It appears specifying a +quartz variant uses

No, +quartz uses OS X's native Quartz graphics:

http://en.wikipedia.org/wiki/Quartz_(graphics_layer)

+x11 uses X11 graphics:

http://en.wikipedia.org/wiki/X11

The XQuartz project is an unfortunately-named package. It is a collection of 
X11 software built for OS X. It provides an X11 interface for OS X. Programs 
communicate with XQuartz using the X11 interface, not the Quartz interface. 
(The Quartz interface is built into OS X and no other libraries are required to 
use it beyond those that come with OS X.)


 2) How does http://xquartz.macosforge.org/ relate to the quartz-wm port? 
 Specifically,
   port install quartz-wm + quartz-wm --version produces version 1.3.1 while 
 the
   XQuartz site shows version 2.7.4 + the XQuartz site implies quartz-wm is 
 part of
   it's code (The quartz-wm window manager included with the XQuartz 
 distribution...)
 
   So to use latest version of XQuartz, does this require installing the .dmg 
 file
   from the XQuartz site?

XQuartz has its own versioning scheme. 2.7.4 only tells you the version 
number of that particular XQuartz collection. It does not tell you the version 
number of quartz-wm or any of the hundreds of other parts of the X11 system 
contained within XQuartz.

Apple used to include X11 in OS X. The way they did so was to include the 
then-current version of XQuartz in OS X. But Apple seldom updated this 
throughout the life of a version of OS X so it became out of date. Users could 
elect to update their X11 manually by installing a newer version of XQuartz. 
Now, Apple has removed X11 from OS X, so if you want X11 at all, and are not 
using MacPorts, you must install XQuartz. This ensures you'll get a current 
version and not an old one.

If you are using MacPorts, then installing the xorg ports is probably better, 
since it keeps more of your software in the MacPorts system (one place to 
update all your software), and it's probably more up to date than XQuartz, 
since each component is updated in MacPorts when it's ready, instead of having 
to bundle them all into a single distribution. The XQuartz package and the xorg 
ports in MacPorts are maintained by the same person at Apple so they are the 
same software.
