[OS X Emacs] LaTeX cannot find its class/style files (obvious fixes attended to)

Thanks Peter!  Your advice worked (see below).

I started with AUCTeX and encountered the problem I described above.  In an
attempt to isolate the source I disabled AUCTeX, and the problem persisted.  So it
seems to occur in both AUCTeX and Emac's latex-mode.

"!which latex RET" in dired-mode yields the same path as when the command "which" is
run in the shell.  On my system that is /opt/local/bin/latex which is the standard
location used by the Macports collection.

Sorry if this was unclear.  The declaration in my .profile uses the corresponding 
correct syntax.

I'm not actually using Carbon Emacs; I'm using the standard GNU Emacs 
through a terminal application (iTerm).  The Emacs I'm running seems to know about
environmental variables set in my bash .profile.

I removed the TEXINPUTS setting from both my .profile, and my .emacs.  LaTeX now
seems to be working as it should in both Emacs latex-mode and AUCTeX.

Thanks again,

Peter
