XCode Command Line Tools 15.0 was recently released, and it contains a
broken version of ncurses 6.0. Some uses of Python's `curses` module
will segfault when compiled with it. The solution is to switch to using
the version of ncurses from Homebrew, which is currently 6.4. Support
for ncurses 6 was added to Python 3.7 and was backported to 3.6 and 2.7,
so this change should not break any recently supported Python versions.

Tested with Python 3.12, 3.11, and 2.7, and all tests in
the `test.test_curses` module pass without issue.

See https://github.com/python/cpython/issues/109617 and
https://github.com/python/cpython/issues/69906 for more information.

Add CPython 3.11.6

Add CPython 3.12.0

It seems that pyenv cannot install 2.7.18 on Mac M1 (Apple ARM).

openssl 1.0.2 does not have ARM support. M1 support was added in 1.1.1i according to
https://www.openssl.org/news/cl111.txt

All include directories should go into CPPFLAGS.
XCode SDK was being added to CFLAGS instead
which caused old Tcl/Tk in the SDK to override a newer one in Homebrew.

Update openssl url for 3.12.0rc2

The old 3.1.1s URL returns a 404

use -I with ensurepip

fix a typo in README.md

According to the POSIX spec, an unescaped backslash not followed by
an escapable character is undefined behavior,
and it has become an error in GNU grep 3.8 (2022-09-02).

The -s flag assures that nothing can be installed to user site-packages
but doesn't keep ensurepip from looking there for Pip.
If Pip is installed in the user site-packages directory, pip won't be installed
for the newly built python -- and its shim won't be created.
-I makes the build install Pip in any case.
The user site-packages installation will override it --
but we'll have the shim at least.

Add CPython 3.8.18, 3.9.18, 3.10.13, 3.11.5

Add CPython 3.12.0rc1

Guthub have recently preinstalled x64 Homebrew OpenSSL to stock MacOS runners. This has caused FreeBSD OpenSSL detection logic to erroneously trigger when running FreeBSD tests in MacOS because their paths happened to coincide.

Replaced checking a specific path with checking with pkg.
