simply add the Quartz file if no X11 and not windows

See MacPorts ticket.

webkit-gtk +quartz was building fine, but I had this error when using py27-webkit-gtk and midori. 
I've run port destroot again and launched the demo program GtkLauncher: it had the same problem. Here is the error:

Dyld Error Message:

  Expected in: flat namespace
I've managed to fix it by adding a previously excluded WebCore/platform/cairo/WidgetBackingStoreCairo.cpp to the build, which implemented the missing method.

Please find the patch attached. It is simplistic because it's only applied when building for Quartz, not X11.
