It took me forever to figure out what was going on.  If you are running the prebuild emacs app, the environment doesn't get inherited.  I now run the prebuild emacs app by opening a terminal window and running open -n /Applications/Emacs.  I can close the terminal window after that, and then that emacs instance will have the environment you expect.  Or at least thats what worked for me.  After that I could install libraries from macports and use them in lisp to my heart's content.
