This does highlight a minor bug in R (an empty string is accidentally
quoted, so the absence of nm on the PATH isn't noted), but your setup
is part of the problem too, I think. How did you install Rtools? (Is it
appropriate here? Is R-pkg-devel a better fit?)

Here's the patch fixing the check (but not the reason why R can't find
nm on your machine):
