Answer 1

I was able to get this running by:

1. cloning your git repo
2. removing the virtualenv==1.8.4 from your requirements.txt
3. git add .
4. git commit -m "removing virtualenv requirement"
5. git push heroku master

I'm assuming you did not git add . and git commit after removing the virtualenv from your requirements. Any changes you make to a git repo will not go in effect, for both github and heroku, until you add and then commit the changes locally, and finally push them to remote repository i.e. Github or Heroku.
