I had this same problem today and this was the issue.

(https://github.com/heroku/heroku-buildpack-nginx/) nginx buildpack includes three .tgz archives (nginx-heroku-18.tgz , nginx-heroku-20.tgz and nginx-heroku-22.tgz ) with compiled versions of nginx for 3 supported Heroku stacks. The buildpack doesn't download and compile nginx when buildpack is compiled, it just extracts nginx binaries from one of these .tgz archives. So the script scripts/build_nginx that you have modified is not run when buildpack is compiled. You need to run make on your machine to run this script. Makefile included in the repo will run the script three times within proper Docker images for the three Heroku stacks and build new .tgz archives, that can be then pushed to your custom buildpack repo.
