Hmm. Thanks, Dirk. That Makefile is downright spooky smart (and worth a study in its own right). I was unaware of the "RHOME" option for R and the "shell" function in GNU make. Given that I had only one *.cpp file in the directory, I got the binary to build simply by typing "make", but I did check that "make <filename>" also appears to work.
