Building cairo with glitz support causes pretty much all apps that link against cairo to fail with forced as-needed. Example gtk+: sr/lib64/libgobject-2.0.so /usr/lib64/libgmodule-2.0.so -ldl /usr/lib64/libglib-2.0.so -lm /usr/lib64/libcairo.so: undefined reference to `glitz_surface_set_transform' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_attach' /usr/lib64/libcairo.so: undefined reference to `glitz_create_drawable' /usr/lib64/libcairo.so: undefined reference to `glitz_find_standard_format' /usr/lib64/libcairo.so: undefined reference to `glitz_drawable_get_features' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_set_filter' /usr/lib64/libcairo.so: undefined reference to `glitz_set_array' /usr/lib64/libcairo.so: undefined reference to `glitz_set_geometry' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_destroy' /usr/lib64/libcairo.so: undefined reference to `glitz_set_rectangle' /usr/lib64/libcairo.so: undefined reference to `glitz_set_rectangles' /usr/lib64/libcairo.so: undefined reference to `glitz_buffer_create_for_data' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_get_height' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_flush' /usr/lib64/libcairo.so: undefined reference to `glitz_composite' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_get_width' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_get_drawable' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_set_clip_region' /usr/lib64/libcairo.so: undefined reference to `glitz_set_pixels' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_get_status' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_reference' /usr/lib64/libcairo.so: undefined reference to `glitz_drawable_destroy' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_get_attached_drawable' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_get_format' /usr/lib64/libcairo.so: undefined reference to `glitz_buffer_destroy' /usr/lib64/libcairo.so: undefined reference to `glitz_add_trapezoids' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_set_component_alpha' /usr/lib64/libcairo.so: undefined reference to `glitz_get_pixels' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_create' /usr/lib64/libcairo.so: undefined reference to `glitz_find_drawable_format' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_set_fill' /usr/lib64/libcairo.so: undefined reference to `glitz_surface_translate_point' collect2: ld returned 1 exit status
This is still a problem of cairo, libcairo should link against libglitz I guess.

cardoe, this is with a system with forced as-needed in the gcc profile, see: http://blog.flameeyes.eu/2008/11/14/problems-and-mitigation-strategies-for-as-needed
Runnning eautoreconf on an ~amd64 system solves this, FWIW.
this is also on a system with forced as-needed: angelos@odin ~ % scanelf -n /usr/lib64/libcairo.so TYPE NEEDED FILE ET_DYN libpixman-1.so.0,libfreetype.so.6,libfontconfig.so.1,libpng12.so.0,libXrender.so.1,libX11.so.6,libz.so.1,libm.so.6,libc.so.6 /usr/lib64/libcairo.so angelos@odin ~ % ldd /usr/lib/libcairo.so|grep glitz angelos@odin ~ % no glitz in there, same result as comment #0
also solved by removing export glitz_LIBS=-lglitz-glx from the ebuild (line 71, cairo-1.8.4)
That was added when James Cloos, who's involved in upstream filed bug #166343. I'd have to evaluate the impact of removal.
(In reply to comment #8) > That was added when James Cloos, who's involved in upstream filed bug #166343. > I'd have to evaluate the impact of removal. Just change it to: glitz_LIBS="$(pkg-config --libs glitz-glx)" The only thing glitz_LIBS contains is, AFAICT, the output of pkg-config --libs glitz but that's a subset of the above.
This is fixed with cairo 1.8.6
