You are correct. I have Python 3.4 installed. Rebuilding on a system with Python 3.5 worked as expected. Apparently if the X-Python-Version is not satisfied, the build gives no fatal errors and appears to work, while not actually building the package properly. But that's a bug for the build system, not this package.
