Gregg,
by default latex won't be on the PATH on OS X, so using no path won't
work. The CRAN binary uses MacTeX which is the de-facto standard
distribution on OS X now and that is what we suggest. If your setup
varies, it's up to you to configure it properly, we can't do that for
you.
Cheers,
Simon

This will only work if latex is installed in that particular path, and
is much less likely to succeed no path prefix, which at least works
as long as pdflatex is on the users path.
