build failure "Error running 'fetch-package' command: Recipe 'glib' not found"

[knlr]

I've followed these instructions for building: https://github.com/EricssonResearch/openwebrtc/wiki/Building-OpenWebRTC

$ cd ~/cerbero \
> && ./cerbero-uninstalled -c config/linux.cbc fetch-package --full-reset --reset-rdeps openwebrtc

WARNING: Error importing command bundlesource:

Environment: Ubuntu 17.10

I tried both the 0.3.0 release and the latest master, same result.
