Comment (by ryandesign):

 Actually, what's weird here is that libpixman is complaining about the
 wrong architecture in libraries belonging to ports that are not
 dependencies of libpixman: atk, cairo, gdk-pixbuf2, glib2, gtk3, harfbuzz,
 pango—ports that can't be dependencies of libpixman since libpixman is a
 dependency of cairo already. libpixman shouldn't be using those. It looks
 like this is happening when libpixman is building its demos. So the port
 should be changed not to build the demos.
