The buildpack writes a templated nginx.conf file to disk during the build phase. This template contains ERB statements to read in environment variables. The buildpack also includes a start script that invokes erb to write out the results of the template before the application is started. With Ruby being removed from the cflinuxfs4 stack, the buildpack can no longer perform the templating operation and results in built applications that will not run.
The buildpack will need to either bring along its own Ruby or be rewritten to not rely upon an installed Ruby for these operations.
