Are you using AUCTeX or Emacs' latex-mode?

Are you able to use dired-mode? Can you position in dired-mode the  
cursor on some file and then press ! followed by

	which latex RET

Two lines will be reported in *Shell Command Output*:

	/usr/texbin/latex
	file.whatsoever: Command not found.

I'm not using MacTeX, so the first line can be wrong. The main  
question is: is the first line same as from a shell when you invoke  
'which latex'?

If your using this statement in both files, then at least in  
~/.profile it's nonsense, because of wrong syntax. It's not that  
useful anyway, because the important variable is TEXMF. *When* the  
right binary is found, then no such TeX related variable needs to be  
set, it's all built-in! And such setting can disable TeX.

The final problem is that Carbon Emacs is no UNIX binary, it's a Mac  
OS X application which is not launched with the help of an auxiliary  
shell. So Carbon Emacs, as all other Carbon and Cocoa applications,  
does not initiate its process environment from the shell related dot  
RC files. http://developer.apple.com/qa/qa2001/qa1067.html explains  
this a bit. You can find more details on the internet – and in the  
Carbon Emacs Wiki: http://www.emacswiki.org/cgi-bin/emacs-en/ 
CarbonEmacsPackage. My advice is to remove the TEXINPUTS settings and  
make sure Carbon Emacs knows the PATH to latex!


Shells can learn from ~/.MacOSX/environment.plist:

	export PATH=$(defaults read "${HOME}/.MacOSX/environment" PATH)
	MANPATH=$(defaults read "${HOME}/.MacOSX/environment" MANPATH)
	export MANPATH
	
	set path=(`defaults read ~/.MacOSX/environment PATH | tr ':' ' '`)
	setenv MANPATH   `defaults read ~/.MacOSX/environment MANPATH`
