Fails for package with a versioneer error

[TheChymera]

This ebuild: https://ppb.chymera.eu/bfa55f.39.4.ebuild
Will fail with this log: https://ppb.chymera.eu/d04e27.txt

Removing the DISTUTILS_USE_PEP517=setuptools line makes it work again.
I talked to upstream and sadly can't get any feedback since I can't actually tell him which command we use for him to test locally, as our command is not vanilla Python, but:

gpep517 build-wheel --backend setuptools.build_meta --output-fd 3 --wheel-dir /var/tmp/portage/dev-vcs/dandi-cli-0.39.4/work/dandi-cli-0.39.4-python3_9/wheel

using this package.

@mgorny any ideas what could be wrong or what I could do to get the actual Python call behind the gpep517 command?

It's upstream bug, filed dandi/dandi-cli#998 with a fix.

For local context: upstream is appending the current directory to sys.path rather than prepending it, so if versioneer is installed in site-packages, it takes precedence over the same-named local file.

Thank you!
