Could be a stale "~/.MacOSX/environment.plist". Do a search on this
list for discussions. You can either run
/path/to/Emacs.app/Contents/MacOS/bin/mac-fix-env , or run M-x
ns-grabenv (or run that in your .emacs) to fix this problem. This is
covered in the manual (first entry under Help menu).
I'm not sure why you don't experience the problem under Carbon emacs.
Aquamacs does the equivalent of ns-grabenv on startup, maybe plain
Carbon does now too?
