[OzTeX] file `pdftex.def' not loaded

[Ken Pierce]

Greetings,

I tried adding these lines to my file, as suggested in the OzTeX faq:

  \ifx\pdfoutput\undefined
  % we are running LaTeX, not pdflatex
  \usepackage{graphicx}
  \else
  % we are running pdflatex, so convert .eps files to .pdf
  \usepackage[pdftex]{graphicx}
  \usepackage{epstopdf}
  \fi


At first, I got an error message saying epstopdf.sty wasn't found. 
So I put a link to it where OzTeX can find it.  But now I get the 
error message

     Package epstopdf Warning: Graphics driver file `pdftex.def' not loaded.

even though OzTeX inputs include

     TeX/Inputs/LaTeX/graphics/

So I tried copying pdftex.def to the same directory as the .tex file 
-- error message is the same.

Advice welcome, with thanks!

Ken
