Custom buildpack that will install pdftk into /app/bin on Heroku. Supports cedar-14.
heroku config:set LD_LIBRARY_PATH=/app/bin
Update the tarball_url line in scripts/build.sh
heroku config:set BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-apt
git push heroku master
Now you'll have a new Heroku app on the default stack (currently cedar-14) that runs the
scrupts/build.sh script in this buildpack. That script will download the most recent PDFTK source and configure it with default options.
heroku logs -t to see when compilation is done. It'll start showing dots..
bin/$STACK/into this buildpack. $STACK shall be the name of your stack as given in the Heroku $STACK variable.
heroku ps:scale web=0 to turn off the dyno.
Copy the snippet above into CLI.
