 I don't understand this commit.

 Previously, the port set `configure.python` to a correct and deterministic
 value on all systems. On Mac OS X 10.7 through macOS 11 inclusive it used
 /usr/bin/python because the OS-supplied version of Python 2 was new
 enough. On Mac OS X 10.6 and earlier, it used MacPorts Python 2.7 because
 the OS-supplied Python 2 was too old. On macOS 12 and later, it used
 MacPorts Python 2.7 because as of macOS 12.3 there is no OS-supplied
 version of Python 2 anymore.

 Now, it uses MacPorts Python 2.7 on Mac OS X 10.6 and earlier, and what
 Python it uses on Mac OS X 10.7 and later is undefined. For example, if
 the user has used `python select` to select some version of Python, it
 seems likely to me that the build will use that Python. That's not
 [wiki:ReproducibleBuilds reproducible], not deterministic, so that's a
 regression.
