Photons block in #global_settings: set a spacing small enough OR a count high enough.
In the objects deffinitions: add a photons block that contain target, refraction on
and reflection on.
You don't realy need a photons block in the light_source unless you want the light NOT
to shoot 
photons (fill light) or it's an area_light and you want the photons to be diffuse
instead of point like.
Another thing, high ambient tend to hide photons effects, many included textures have
exessive 
ambient values as left over from early versions.
