Hello.
They may have already been found and are beginning to be fixed.
But it may not be yet, so I'm writing about it here just in case.
The environment is 12.4-STABLE amd64.

In a clean environment like poudriere, python is not found and a configure error occurs.

In an environment where various ports have already been installed, the following message will appear.

/bin/sh: no: not found
*** Error code 127

Stop.

This is because CLANG_FORMAT is set to no when clang-format is not found.
But after this, it checks that the length of CLANG_FORMAT is 0, so it tries to do "no".


Regards.
