django - My custom heroku python buildpack downloads requirements on every push -

i forked default python buildpack , added few lines add together phantonjs , casperjs executables environment. code here: https://github.com/tapanpandita/heroku-buildpack-python .the changes made minimal (from line 163-196 here https://github.com/tapanpandita/heroku-buildpack-python/blob/master/bin/compile#l163).

however, now, problem when force heroku master, requirements downloaded again. makes deployment process slow. wasn't problem before when using default buildpack. thought might have done wrong? it's django app.

try changing buildpack can vendor phantomjs , casperjs executables in repo.
