It would be good not to need to search for a r-sig-mac posting but rather refer to a "central document".

As a matter of completeness, PATH=$PATH:/user/texbin did not alter my path 'globally', and immediately broke in a new terminal tab.  

I solved the issue globally with

sudo sh -c 'echo "/usr/texbin">>/etc/paths.d/texbin' [the reader should be warned I use bash by default on my terminal]

which does work if I use R in a terminal and I call system('pdflatex --version'). This solution also allowed a perfectly clean R CMD check.

On the other hand, from the GUI [R.app GUI 1.40 (5751) x86_64-apple-darwin9.8.0], 

> system("pdflatex --version")
/bin/sh: pdflatex: command not found
