Well, 'dtraceall' claims dependency on all the provider modules, so results in everything being loaded including dtnfsclient. In theory, dtnfsclient and other providers should contain the necessary module dependencies to cause them to load everything they depend on, but I also have the feeling I've run into the problem you're seeing. Could you provide the symbol missing errors from the console? It should be fairly easy to track down the missing graph edge using that. Robert N M Watson Computer Laboratory University of Cambridge
