Hi Randall,
On Tiger, I would've agreed with you. On Leopard, X11 is installed by
default, so I don't see a lot of value in assuming it is *not* present.

I would like to suggest that the variants +quartz and +x11 should be
supported where relevant, eliminating the use of the +no_x11 variant:
+quartz Enable building the port to render graphics using the quartz
engine and aqua user interface
+x11 Enable building the port to use X11
Furthermore, I would like to suggest that these variants should
never be default variants and that we should modify the macports
base to recognize that a port has these variants and if neither is
selected (either at the command line or in variants.conf) that an
error message should be displayed explaining that the port may be
installed with either: +quartz, +x11, or +quartz+x11, although some
ports may result in unpredicatable behavior if +quartz+x11 is used.
Furthermore, I would like to suggest that the +no_x11 variant and
the +no_quartz (if it is used at all) variants should be actively
discouraged.
Background:
I have removed X11 from my laptop and am building (albeit slowly)
and using applications that I used to run under X11 under Aqua or am
using an Aqua-based (roughly) equivilent application. This has
revealed a number of instances of ports assuming that X11 is
installed on a Mac OS X box, when that assumition is or should be
false, such as when the upstream project is supporting Quartz-only
builds, or when the project actually only really cares if GTK+ is
installed, but the port hauls in X-based dependencies anyway. Some
ports even build both the X11 and Quartz libraries for the port, but
then only advertize to subsequent and dependent builds only the
Quartz library.
While working through this, I realized that we should assume that
X11 is not available on a machine and that we should re-gin our
ports to match that assumption. Right now the assumption for most
ports is that X11 is installed on a machine, and that users would
prefer items that provide both X11 and Quartz should always provide
X11 versions and should only maybe provide Quartz versions.
