[OS X TeX] Unknown Graphics Extension

[Ralph Martin]

It seems that the class file I was using was testing for pdf in an 
incorrect way.

I am reporting the fix here (given by Thomas Esser - thanks, Thomas) in 
case
other users find it useful if they are using the egpubl.cls class, or 
other similarly
broken class files:

Replace

     \newif\ifpdf  % determine if we are running PDFLaTeX or not
     \ifx\pdfoutput\undefined \pdffalse % we are not running PDFLaTeX
     \else
       \pdfoutput=1 % we are running PDFLaTeX
       \pdftrue
     \fi

by

     \RequirePackage{ifpdf}


Best wishes

Ralph
