Since it appearently doesn't, is the underlying problem that the problem is too complex to be handled by a dependency system like macports's? This is the sort of problem that makes the nix package system look more attractive. Though it may also be (a lot?) harder to use.

The necessary list of +quartz dependencies for inkscape +quartz are:

cairo                          @1.14.8_0+quartz+x11
pango                          @1.40.3_1+quartz+x11
gtk2                           @2.24.31_0+quartz
cairomm                        @1.10.0_3+quartz+x11
pangomm                        @2.36.0_0+quartz+x11
gtkmm                          @2.24.5_1+quartz
gtkspell2                      @2.0.16_6+quartz

inkscape +quartz works fine with gdk-pixbuf2 installed with either +x11 or no variant (-x11)

As has been mentioned elsewhere gtk2 can only be installed either +quartz or +x11 so you can not have it both ways.  The
best approach is decide whether you want to build a +quartz environment or an +x11 one and only install ports
that are consistent with said environment.  +x11 provides the best coverage and  borth inkscape +x11 and inkscape
+quartz work fine for me.  inkscape actually doesn't contain any X11 or Quartz specific code and so
the difference is strictly determined by the gtk2 backend in use.

Bottom line you can't just install mixed +x11 and +quartz ports without expecting to run into conflicts.  In this case
the conflict is gtk2 because it only supports one backend at a time.  cairo and pango install multiple backends at
the same time but in this case the app using them needs to use the correct backend specific API to select the backend
it wants.

So if you install inkscape +quartz then you probably want to install gimp2 +quartz as well (and not install any gtk2
ports that depend on gtk2 +x11)

The additional required +quartz ports are

gegl                           @0.2.0_24+quartz
libglade2                      @2.6.4_8+quartz
librsvg                        @2.40.16_0+quartz
py27-pygtk                     @2.24.0_3+quartz
