Yes. You have a UNIX style installed emacs that happens to use the NS
term. The app bundle is only provided as a helper for running it from
the GUI.

How do you propose we find the .pdmp file in the app bundle, which can
be put *anywhere*, when you run 'emacs' from the command line?

If you want to use the app bundle and expect Emacs to load files from
within the bundle, don't use a UNIX style install.

If you must have two different UNIX style installs of Emacs then
you'll have to use different prefixes or something. Someone who knows
more about the way emacs installs may have a better idea, but this
isn't a bug.
