I believe the parser has moved to this Python package https://github.com/kronenthaler/openstep-parser, could someone give a try at updating or changing the dependency and using the openstep-parser.
I'm not sure if changing this dependency could cause a break in the latest version of glyphsLib.

listed as a dependency in requirements.txt, it was previously at https://github.com/fonttools/openstep_plistI believe the parser has moved to this Python package https://github.com/kronenthaler/openstep-parser, could someone give a try at updating or changing the dependency and using the openstep-parser.
