I have to do this with my $PATH setting in order to be able to run certain shell scripts from within ESS. My recollection is that some of the other pre-packaged versions of emacs for OSX (eg. Aquamacs, Carbon Emacs) have locally added init code that does this invisibly.

Just as a shameless plug: my Emacs distribution for OS X (http://vgoulet.act.ulaval.ca/emacs/mac) also does it out of the box. Actually, I lifted the code from Aquamacs.

This distribution is getting in pretty good shape. It's the one I use every day now and I think it is pretty good for those who want to stay close to the standard GNU Emacs. It is not Mac-ified at all. Like my Windows distribution, it comes with ESS and AUCTeX loaded.
