[Rd] depending on orphaned packages?

Or, a crazy person (me) cld volunteer to keep this running and get it back on CRAN.
I fixed the severe warning and also added C-side registration code.
The pkg is monolithic but the C code is super straightforward (a is the R code).
Unless someone can think of a reason not to, I can submit this to CRAN this week and get the source up on social coding sites.
It looks like Jerome Braun did this for another one of Bob Wheeler's pkgs, so there's some existing precedent for doing this.
