Packaged Python framework is missing XML libraries on macOS

[Alessandro Gatti]

Reproduction steps:

- Open a fully annotated schematic.
- Bring up the BOM generation dialog.
- If no plugins are present, just add one from the list of packaged plugins.
- Try to generate a report without changing the python commandline (I am using bom_html_grouped_by_value as BOM generator plugin).
- The following error occurs:

Run command:
python "/Applications/KiCad/kicad.app/Contents/SharedSupport/plugins/bom_html_grouped_by_value.py" "/Users/agatti/***/***/***/***.xml" "/Users/agatti/***/***/***/***"

Command error. Return code 1

Actually, if you could file this over at https://github.com/KiCad/kicad-mac-builder, this is a macos packaging issue, and that's where I fix those. :) Thanks!

Fair enough - did just that: https://github.com/KiCad/kicad-mac-builder/issues/227

According to the discussion in the mac packaging bug tracker, this bug is just a symptom of the Eeschema python path problem.
