The missing symbol is:

std::shared_ptr<DependencySpecTree::NodeType<paludis::LabelsDepSpec<paludis::DependenciesLabel>>::Type>
paludis::spec_tree_internals::BasicInnerNode<paludis::SpecTree<...>>::append<
        paludis::LabelsDepSpec<paludis::DependenciesLabel>>(
            std::shared_ptr<paludis::LabelsDepSpec<paludis::DependenciesLabel> > const&)

=> Move LabelsDepSpec<DependenciesLabel> instantiation to header file

Missing dep_spec.hh include:

133: >>> test action_TEST

=> Provide full type for NamedSetDepSpec
