What appears to be happening is Heroku only has version 1.9.7 of bundler, but Pakyow requires a version greater than 1.10. However, when I deploy a brand new app it looks like Heroku is bundling with 1.9.7 and doesn't try to install the version that Pakyow requires.

Scratching my head right now. I suppose it could be a difference in how Heroku handles Windows vs non-Windows, but I don't have a Windows machine to test that out. I do know of a few people who have successfully deployed a Pakyow app to Heroku from Windows in the recent past. I might reach out to them to see if they can help here.
Another clue is that the
Procfile is optional -- a Pakyow app will run on Heroku without it. Just to make sure you're using the right stack, what's the result of
heroku info? Here's mine:
