Hi Pierre-Elliott, Thanks a lot for the report and investigating the cause of failure. I've recently taken over the package maintenance for global and have been chipping away at the backlog of known issues (including updating the version in Debian to something more recent :) ).
I was able to confirm that the pygments parser plugin wasn't working due to the missing python script. The broken behaviour is fixed once pygments_parser.py is installed with the package. I'll shortly upload an update with the script included. You'll also need to change the "*.la" references in your config file to "*.so" references (e.g., replace "pygments-parser.la" with "pygments-parser.so") as the static versions of the plugin libraries are not shipped with the package. Please shout out if you still face issues after the update. Thanks, Punit
