[Rd] Problem cross-compiling on Ubuntu

I'm new to building packages that have source code and I didn't know
about that site. In any event, it is an experimental private build for
testing, and it is more convenient for me to do most of the testing in
a Windows environment. I've spent a lot of time failing to build from
source on Windows, and would prefer not to name myself as maintainer
of someone else's package.
But, since it looks like that might be the easiest route, I've just
let the maintainer know what I'm up to and asked if he's fine with me
