MacOS build-installer: ncurses patch file not available via ftp

[itamaro]

Bug report

Bug description:

I am trying to build a MacOS installer, following the instructions and build script here (from the 3.12 branch, fwiw, but the same issue exists on main).

The build-installer script attempts to download various third-party dependencies, including this ncurses patch. This fails for me due to invalid ftp login.

I think I found the same patch here. Downloading it manually, I was able to verify the md5 is identical to the one specified in the installer script, so it seems legit.

We can either update the build-installer script to use the http URL instead, but I was wondering whether it would be a better idea to switch over to using https://github.com/python/cpython-source-deps instead? (a bigger refactor, but probably better for the longer term)

CPython versions tested on:

CPython main branch, 3.14, 3.12

Operating systems tested on:

macOS

Thanks for the report. As of the Python 3.14.0 alpha 5 pre-release and the upcoming 3.13.3 and 3.12.10 releases, python.org macOS installers now build and link with ncurses 6.5, the current stable release and thus the missing patch file is no longer needed or used.
