Dear Berend and Simon, I've now tried Berend's solution and it appears to work fine: If necessary, I add /usr/texbin to the path when the Rcmdr GUI starts up and restore the path to its previous state when it closes.
I agree that Simon's solution will be more flexible since it should work if pdflatex is located elsewhere (as long as it's on the path reported by path_helper), and I'll give that a try as well.
