carla: ARGS="--package package_name" Causing errors when importing

I’m on Ubuntu 18.04. I was following the source map ingestion guide, and the name of package caused an error.

make import ARGS="--package carlanoloops":

At the top is says that package is an unknown option, but that is what the docs says to do.

Running make import without package works, but will only work the first time (as mentioned in the docs).
