Could be an easy one nevertheless as it is not the library but just a
subpackage that adds the dependency:

  # repoquery --whatrequires librsvg2|grep cairo
  cairo-clock-0:0.3.4-5.fc15.x86_64

Perhaps the clock can be disabled at build-time easily. A switch added
to the spec file could then also disable the subpackage.
