Those two are actually the same
thing. /Applications/Emacs.app/Contents/MacOS/emacs is just the
executable file hidden inside the Emacs.app bundle. So it really does
depend on starting from the Terminal and picking up your PATH
settings.

Yes, I'd try adding your /opt directories to `exec-path' first and see if that
fixes
the problem. You can either something like the (setq exec-path (append ... ))
solution in my last email, or the following:
(add-to-list 'exec-path "/some/path/here")
Note that you might *also* need to set the environment PATH variable
from within Emacs; that's the line with `mapconcat' in my prev
email. As I said, I forget exactly how each of these things interacts
with shell-mode's tab-completion.
If that works, the nicer solution would probably involve having your
.emacs run a short shell script to print out and parse the value of
PATH set in your .bashrc (or wherever), and set PATH and `exec-path'
based on that. I'll try and work out a quick hack for this later this
evening, if someone doesn't beat me to it ;-)
cheers,
Jonathan
