Having had a bit more time to look through the doc: in the  
documentation for teTeX itself, at /Library/teTeX/share/texmf/doc/ 
tetex/TETEXDOC.pdf, you'll see more detail about the change that was  
introduced in the underlying TeX engine. This is (briefly) explained  
in section 4.6:

"4.6 pdfetex: the new default TEX engine
teTEX uses pdfetex for all formats except “good-old” tex. So, if you  
run latex, the
underlying engine will be pdfetex. Some (broken) TEX macros assume  
that pdfTEX is
running in PDF generation mode if they detect primitives that pdfTEX  
has introduced
(e.g. \pdfoutput). This is wrong, since pdfTEX can also be used (and  
is used) to gen-
erate DVI output. A reliable way of detecting PDF output mode is  
implemented in
ifpdf.sty which works for plain TEX as well as LATEX."
