d_materialise_unique() is gone in Al's fs tree:

[mandatory]
        d_materialise_unique() is gone; d_splice_alias() does everything you
        need now.  Remember that they have opposite orders of arguments ;-/

Maybe it's worth basing your git tree on top of Al's rather than a random
-rc, since it's now a filesystem?
