Failure with bdist_wheel and namespace packages

I’m relatively inexperienced with setuptools, but I’m attempting to create a module that makes use of new-style native namespace packages. Most things work fine, including sdist - but bdist_nuitka fails with the following :

(venv) [gdude@ns348665 Sidecar]$ python setup.py bdist_nuitka
running bdist_nuitka
running build
running build_py
creating build
creating build/lib
creating build/lib/comect
creating build/lib/comect/sidecar
copying src/comect/sidecar/__init__.py -> build/lib/comect/sidecar
Traceback (most recent call last):

Running with -O will skip asserts, so for the hell of it I gave that a try too.

(venv) [gdude@ns348665 Sidecar]$ python -O setup.py bdist_nuitka
running bdist_nuitka
running build
running build_py
Nuitka:INFO:Recurse to import 'comect.sidecar' from 'comect/sidecar'. (Module is exact match of 'comect.sidecar' instructed by user to recurse to.)
Nuitka:INFO:Recurse to import 'comect' from 'comect'. (Containing package of recursed module 'comect.sidecar'.)
Nuitka:INFO:Included compiled module 'comect'.

Nuitka:INFO:Included compiled module 'sidecar'.
error: [Errno 2] No such file or directory: '/home/gdude/Comect/Sidecar/build/lib/comect.sidecar'

This results in the following file structure:

It looks to me like a simple enough issue, but I’m not 100% sure whether I’m doing something wrong. Any ideas?

Environment details

Python: 3.7.3 Nuitka: 0.6.4 (Installed with pip into a virtualenv) Platform: Arch Linux, x86_64

Example code can be found at this commit - this is the actual project I’m working with.

Thanks in advance!
