Could you try brew cleanup -s to clear the existing cache?

I get the same error after running your command.

It seems brew doesn't download this file. When I manually downloaded it and put it in the place brew expects the install worked (though in my case it was an upgrade.)

This has started to occur for me recently:

==> Upgrading railwaycat/emacsmacport/emacs-mac
  emacs-28.2-mac-9.1 -> emacs-29.1-mac-10.0 --without-modules --with-natural-title-bar --with-native-comp

For anyone that hits this error, a workaround is to download the file yourself from the recipe and put it in the place the formula expects, eg:

curl https://raw.githubusercontent.com/railwaycat/homebrew-emacsmacport/911412ca8ea2671c1122bc307a1cd0740005a55d/patches/emacs-mac-title-bar-9.1.patch > ~/Library/Caches/Homebrew/downloads/fc68c1c12db24bc6d0b2efaf57f5b6d5fc4975e17abae8e7607b8bad24a81431--emacs-mac-title-bar-9.1.patch

(Note that the gist url should come from the recipe and the path you're saving to will come from the home-brew error message on your machine)
