 I found this issue while investigating #64425.

 When source code of Python project contains a script called `build.py` or
 a submodule called `build` it will override global installation of the
 {{{build}}} tool. This is when MacPorts invokes {{{/path/to/python -m
 build ...}}} local script/module will be invoked instead of intended tool.
 In such cases pep517 build will always fail.

 Issue begun after [e94c8a1f8531ced6e1d765849193e36a590425c9/macports-
 ports] and so far I found that it affects {{{py-pendulum}}} port.
