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.

Indeed, I tried that some time ago, and it did not work.
