 In 2.8.3, I couldn't find the "x11" dependency you mention, this is
 what I saw in gdk-2.0.pc:
    Requires: gdk-pixbuf-2.0 pango pangocairo fontconfig xcursor
 (Other pcs:
 gdk-pixbuf-2.0.pc:      Requires: gobject-2.0,gmodule-no-export-2.0
 gdk-pixbuf-xlib-2.0.pc: Requires: gobject-2.0,gmodule-2.0,gdk-pixbuf-2.0
 gdk-x11-2.0.pc:         Requires: gdk-pixbuf-2.0 pango pangocairo
                                   fontconfig xcursor
 gtk+-2.0.pc:            Requires: gdk-x11-2.0 atk cairo
 gtk+-x11-2.0.pc:        Requires: gdk-x11-2.0 atk cairo
 )

 I checked the configure script for Gtk 2.8.3, it only adds x11 to the
 Requires if pkg-config finds a x11 package.  I couldn't find relevant
 changes after 2.8.2, but found:
2005-08-15  Owen Taylor  <otaylor at redhat.com>

        * configure.in: Add -lXext to GDK_EXTRA_LIBS in absence of pkg-config
        files for x11/xext. (Jonas Bonn)

 or:
2005-08-15  Owen Taylor  <otaylor at redhat.com>

        * configure.in: Fix have_base_pc / have_base_x_pc typo.

        * gdk/x11/gdkdrawable-x11.c gtk/gtksettings.c: Remove panoxft.h includes.
        (#313417, James Andrewartha)

        * configure.in: Add fontconfig to X_PACKAGES, since we use it for
        FcNameConstant(). (More of #313417)

 Anyway, x11 isn't a problem here, and even if xcursor might have been a
 problem, libxcursor-dev ships a .pc.  xcursor Requires xrender, and
 xrender Requires nothing.
   I checked pango and pangocairo, and I'm quite sure for fontconfig, so
 everything seems ok to me.

 (Surprisingly, the packages are supposed to be comma-separated, not
 space-separated, but a lot of pkg-config files seem to use spaces.)

 Please provide a way to reproduce your build failure so that I can
 diagnose which pkg-config is to be fixed.

   Thanks,
