Re: [release] Boost 1.67.0 Beta 1 Release Candidate 1

Hi,

I wonder whether anyone from the Boost.Build project would be able to
comment, and can explain the error message.
It's true I relatively recently added
https://github.com/boostorg/python/commit/d4d41d94aecc9f8098aabd3587fcb95458451f71,
but I don't see how this could cause the observed error (which doesn't
seem to be about a failed Python detection, but about an internal
Boost.Build error (to detect the `python.python_for_extensions` rule).

I can't reproduce the problem myself. From the generated output it seems
as if passing `--without-python` would suppress the failure, but that
hadn't been necessary before, or has it ?

Thanks,
