[Rd] depending on orphaned packages?

Ah, I spoke too soon. I started putting the demo code into a test suite and ran one check with valgrind and — sure enough — there's def more issues (a cpl functions) than the overt/easy ones (and, I went back to the check results page and, also sure enough, they're there, too). They look to be fairly straightforward to resolve but it's going to take a bit longer than "this week", but I'm not rescinding the volunteering.
