I recently came across the same problem reported here:
http://tolstoy.newcastle.edu.au/R/e6/help/09/04/12383.html The fix was to edit "$R_HOME/etc/Renviron" and change R_PDFLATEXCMD=${R_PDFLATEXCMD-${PDFLATEX-'/usr/texbin/pdflatex'}} to R_PDFLATEXCMD=${R_PDFLATEXCMD-${PDFLATEX-'pdflatex'}} with similar modifications to the other TeX-related commands.
