I am trying to publish my site on an Amazon's EC2 Instance, and I keep getting a 500 error. I really dunno why.

I know that this is an old thread but I've just bumped into the same issue and I don't think that this is caused by a missing package. As the Django core distribution contains the correct wsgi handler already.
The problem here is that when wsgi.py is executed it's missing the packages of the site-packages from your virtualenv. (If you have activated your virtualenv, and done pip install django then everything is fine. You have the necessary django packages).
As far as I'm concerned, I fixed the issue modifying the sys.path in my Path/to/Project/Project/wsgi.py file.
You have to append your project dir and your virtualenv site-packages to the sys.path List. Here is my wsgi.py file contained in my project (Talking about the wsgi.py created with django-admin.py start-project)... that I had to modify in order to make it work with Apache
# =====================
# wsgi.py file begin
import os, sys
# add the hellodjango project path into the sys.path
sys.path.append('<PATH_TO_MY_DJANGO_PROJECT>/hellodjango')
# add the virtualenv site-packages path to the sys.path
sys.path.append('<PATH_TO_VIRTUALENV>/Lib/site-packages')
# poiting to the project settings
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "hellodjango.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
# wsgi.py file end
# ===================
Make sure:
you added mod_wsgi to the Apache modules dir mod_wsgi must be compiled for the OS, Apache and Python version you have
added the load module command into your httpd.conf to load mod_wsgi module LoadModule wsgi_module modules/mod_wsgi.so
configured Django specifics in your httpd.conf or any conf you include in your httpd.conf
Based on the documentation How to use Django with Apache and mod_wsgi
WSGIScriptAlias / <PATH_TO_PROJECT>/hellodjango/hellodjango/wsgi.py
WSGIPythonPath <PATH_TO_PROJECT>:<PATH_TO_VIRTUALENV>/Lib/site-packages

Hope this helps. It worked for me.
