Problem/Motivation

The system packages pango-dev and cairo-dev are not installing. I was running Node-RED 7.2.2 and everything was fine at the morning. Then I updated to Node-RED 7.2.3 and I got that error. I had in mind that it was a too old NPM Node last time so I reverted the snapshot from 0400am: same problem. Then I restored the whole VM from 0300am: same problem.

Expected behavior

I had this two system packages in my configuration for the colorthieve-node and had no problem. They should install without a problem.

Actual behavior

Steps to reproduce

Put this into the configuration:

system_packages:
  - build-base
  - musl
  - make
  - g++
  - jpeg-dev
  - imagemagick
  - pango-dev
  - cairo-dev
npm_packages:
  - fs-minipass
  - minizlib
  - color-thief-node

Proposed changes

Node-Red starts with Default Configuration. Then I updated every node to get a clear start point.
