This commit allows building Python with the following libraries
installed via MacPorts:
- ncurses
- openssl
- readline
- zlib (XCode SDK zlib is still tried first)
If either Homebrew or MacPorts system is the only one installed, that system
will be used automatically.
When both systems are installed, then whatever is found first in PATH - brew
or port - will be used for all dependencies.
The following environment variables can be set to non-empty value to override
the selection:
PYTHON_BUILD_USE_HOMEBREW
PYTHON_BUILD_USE_MACPORTS
Tcl/Tk specific support is omitted due to CPython incompatibility with
Tcl/Tk 9, according to the comments in use_homebrew_tcltk().
Those who need Tcl/Tk module, can use PYTHON_CONFIGURE_OPTS --with-tcltk-libs=
pointing to the Tcl/Tk location which can be installed either from sources or
via MacPorts.
Tests for added *_macports_* functions are based off of the corresponding
brew counterparts.

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.
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.
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.
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.
