Configuring graphics/imlib2-20060926 from ports without X11 will make the configure script break.
The port will correctly use the --without-x switch but the configure script still can't find X11 libs and
headers (no surprise there) but also cannot tell that --without-x was used.
Exerpt from the configure script:

if test "x$have_x" = "xno"; then
   # If --without-x was passed, this will be "disabled" instead of "no" --
   # so always treat "no" as an error
   { { echo "$as_me:$LINENO: error: no X support found.  Use --x-includes and --x-libraries to specify the X
path on your system, or --without-x to disable X support." >&5
echo "$as_me: error: no X support found.  Use --x-includes and --x-libraries to specify the X
path on your system, or --without-x to disable X support." >&2;}
   { (exit 1); exit 1; }; }
fi

This would make you think that the switch is used correctly but still the variable $have_x has value "no",
even with the --without-x switch.

Fix: Editing the configure script and inserting the line:
have_x="disabled"
makes imlib2 configure and build, this is what the script expects.

How-To-Repeat: 	1) Do not install X11 libraries and headers or uninstall them.
	2) put WITHOUT_X11=yes in /etc/make.conf
	3) cd to /usr/ports/graphics/imlib2
	4) run make as root
	5) Get error message about missing X11 stuff
