I am getting the following error when trying to collectstatic as a part of deploy on Heroku. The only package that seems to interact with ghostscript is PIL which may get installed via django-easy-thumbnails:

-----> $ python manage.py collectstatic --noinput

I can't find anything on this error, can someone render assistance with things to help troubleshooting?

I have tired:
- Explicitly installing pillow in my requirements.
- Clearing heroku app cache
- Ensuring the python runtime was the most recent

I checked docs on heroku stack, and it shows that ghostscript is part of the environment packages:
https://devcenter.heroku.com/articles/stack-packages

I just checked on the server, and this file exists:
