Compilation of v3.9.0b1 fails on macOS

Followed the instructions in the CPython Internals book explicitly and unable to compile v3.9.0b1. Unable to continue with the book...

Steps & output as follows:

Cloned repo and checkout version stated in book

> git clone git@github.com:python/cpython
> cd cpython
> git checkout tags/v3.9.0b1 -b v3.9.0b1
Updating files: 100% (4849/4849), done.
Switched to a new branch 'v3.9.0b1'

Check Xcode command line tools installed


> xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" in System Settings to install updates

softwareupdate --history | grep Xcode Command Line Tools for Xcode 15.1 08/01/2024, 12:51:10

Check Homebrew installed
```
> brew --version
Homebrew 4.2.17
```

Install dependencies via homebrew

> brew install openssl xz zlib gdbm sqlite
Warning: openssl@3 3.2.1 is already installed and up-to-date.

Warning: gdbm 1.23 is already installed and up-to-date.

Run config script with homebrew zlib


> CPPFLAGS="-I$(brew --prefix zlib)/include" \
LDFLAGS="-L$(brew --prefix zlib)/lib" \
./configure --with-openssl=$(brew --prefix openssl) --with-pydebug

I've truncated some output, see below

configure: creating ./config.status config.status: creating Makefile.pre config.status: creating Misc/python.pc config.status: creating Misc/python-embed.pc config.status: creating Misc/python-config.sh config.status: creating Modules/ld_so_aix config.status: creating pyconfig.h creating Modules/Setup.local creating Makefile

I've truncated the output from config script. See [this gist](https://gist.github.com/bradenmitchell/2d04d2b9e4baf3dd69fd37b44556a8b1) for full output.

6. Check Makefile, etc. created
