Hi,

my best guess is that the package previously used python-build-system
instead of pyproject-build-system. The latter basically builds a zip file
(wheel) of everything and extracts it to site-packages. Zip files don’t
include the +x bit and so it gets lost in the process.

I believe this is a bug in the package. It should either indirectly call
these files via the python3 executable or mark them as entry points[1],
so pyproject-build-system can put an executable into /bin.

Perhaps (chmod file #o755) instead of (invoke …)? Otherwise should be
fine to get it working again.

Cheers,
Lars
