Reproduce the Odoo 12 installation and the web.assets_backend compilation using the SCSS files listed in the report. Start by tracing why the bundle encounters "#! /usr/bin/perl" while processing the listed assets. Done means the installation completes and the backend asset bundle compiles without this CSS error.
