Geo-Django on Heroku throwing "No such file": libjasper.so.1

[lakeshow]

Heroku-16, Django==1.11.8  

Any `heroku run python manage.py x` command will throw:  

OSError: libjasper.so.1: cannot open shared object file: No such file or directory

According to this issue here: https://github.com/cyberdelia/heroku-geo-buildpack/issues/43, heroku-16 is without libjasper at runtime.  

It was apparently solved by user @dschep here: https://github.com/TrailStash/heroku-geo-buildpack/commit/5ae45e57353aab6a9fb2f0443e9ea0974d8b29ba  

However for me and others, the same issue remains even when using the forked buildpack. Libjasper is nowhere to be found.   

Anybody push through this?  

some personal settings:  

import dj_database_url
from os import environ

DATABASES['default'] =  dj_database_url.config()
DATABASES['default']['ENGINE'] = 'django.contrib.gis.db.backends.postgis'

GEOS_LIBRARY_PATH = "{}/libgeos_c.so".format(environ.get('GEOS_LIBRARY_PATH'))
GDAL_LIBRARY_PATH = "{}/libgdal.so".format(environ.get('GDAL_LIBRARY_PATH'))
PROJ4_LIBRARY_PATH = "{}/libproj.so".format(environ.get('PROJ4_LIBRARY_PATH'))

A full traceback in case:
