py27-bcrypt @3.1.7, py27-cffi @1.16.0: This CFFI feature requires setuptools on Python >= 3.12. The setuptools module is missing or non-functional.

py27-bcrypt @3.1.7 fails to build from source for me on macOS Sonoma x86_64:

SyntaxError: invalid syntax

I don't know why the error message (which comes from py27-cffi) mentions "Python >= 3.12"; this is Python 2.7. The file the error message is in is new in py27-cffi @1.16.0. Installing py27-cffi @1.15.1 works around the problem.

This issue came up for me today when trying to set up a macOS Sonoma buildbot worker since these ports are in the dependency chain for buildbot-slave-0.8. For now I will copy the old py-cffi @1.15.1 Portfile and files directory into the private ports collection that I use for the buildbot machines.

I guess the actual error is SyntaxError: invalid syntax, but it occurred while trying to show a message specific to Python >= 3.12 which still seems off.

Drop support for end-of-life Python versions (2.7, 3.6, 3.7).

This also blocks py27-cryptography which itself is a dependency for a bunch of other ports. Everybody might have dropped support for Python 2.7 for good reasons but there are still actively developed tools that have old references to Python 2.7 versions of libraries.

In c05f80b73c95c2e9591f4577a0771bda0bb097ea/macports-ports (master):

py-cffi: use last supported version for py <= 3.7

Fixes: #68466

For searchability purposes, this affects py27-pynacl, too
