Allegrograph / Sesame HTTP Server

Playing with the Allegrograph Sesame REST protocol.
My CL is minimal. I can't start the Sesame HTTP server against an RDF store.

e.g.

$ rlwrap ./alisp                                                               
                                                        (09-12 00:48)

It starts but I always get a 404 no matter what I do. (I've tried opening /
creating a triple store before I start the sesame server.

What am I doing wrong??

Thanks,
