I have spent days trying to get the outdated libvips buildpacks working on Heroku. I finally got https://github.com/wwarne/heroku-buildpack-vips to work, but it doesn't seem to have been compiled with libpoppler, so I don't have pdf support which I need. I have tried repeatedly to run the build.sh file, but I have not been successful.
Does anyone know of a way to get libvips installed on heroku with poppler pdf support without adding 200mb to my slug by using apt-get install?
