emacs-mac-app missing idlw-bindings.el

In /Applications/MacPorts/EmacsMac.app/Contents/Resources/lisp/progmodes the idlwave library depends on several files, one of which (idlw-bindings.el) is missing. This causes the symbol "idlwave-code-abbrev" to be 'void'.

idlwave has been unmaintained for quite some time (a few years, I think), so there shouldn't have been any changes that would result in the removal of this file. And there are failures from other parts of the library which clearly expect this macro to be defined. My suspicion is that this is simply an oversight.

A file by that name (idlw-bindings.el) doesn't exist in the Emacs source. It's plausible it could be generated at build time, but I also note in the changelog:

(idlwave-code-abbrev): Delete macro.

So I don't really know how this stuff is supposed to work, but it looks like you're expecting things to look like they did pre-2021.
