Please bottom post, it makes the conversation easier to follow. Could
you include your config?

I haven't seen this error before, it appears to me that the Chromium
build is attempting to run a script called cups_config_helper.py, and
it doesn't exist. This file should be part of the source distribution.
I have it in my tree at
output/build/chromium-67.0.3396.79/printing/cups_config_helper.py.

We could also probably make cups/printing support an optional
dependency, based on whether or not cups is enabled.

Lastly, these patches are based on the master branch. Could you retry a
clean build on that branch?

Best regards,

Joseph
