ImportError: No module named mysite.wsgi message when deploying heroku app

Question

-Mac OSX 10.7.5 -Python 2.7 -PostgreSQL 9.3.2 (set up via Heroku) -Django 1.6

I get an "Application Error" message when I go to the site url. I do have a mysite/wsgi.py file and here's what's in it:

import os

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
from django.core.wsgi import get_wsgi_application
from dj_static import Cling

application = Cling(get_wsgi_application())

My Procfile contains

web: gunicorn mysite.wsgi

When I run "foreman start", I get:

23:53:02 web.1  | started with pid 709
23:53:02 web.1  | /usr/local/foreman/bin/foreman-runner: line 41: exec: gunicorn: not found
23:53:02 web.1  | exited with code 127
23:53:02 system | sending SIGTERM to all processes
SIGTERM received

"Heroku logs" gives me:

From the "foreman start" results, I gathered that perhaps gunicorn wasn't properly installed, so I downloaded a .gz and did "sudo python setup.py install" and "import gunicorn" showed that it installed properly. Then I did "git push heroku" once again, but I'm still getting the same error. Does anybody have insight into what might be going on here? thnx.

The issue, it turns out was that I had added the init.py file in my app folder to .gitignore. As a result django wasn't recognizing my app folder as a module, hence the import error. Removing the init.py file from .gitignore resolved the issue.
