trying for the first time to use mod_wsgi for my pyramid application, but I keep getting ImportError: No module named deploy when trying to access the site
in my /etc/apache2/sites-available/domain.com
<VirtualHost *:80> ServerName domain.com ServerAlias www.domain.com ServerAdmin admin@domain.com DocumentRoot /data/app ErrorLog /data/app/apache_error.log WSGIApplicationGroup %{GLOBAL} WSGIPassAuthorization On WSGIDaemonProcess pyramid user=www-data group=www-data \ processes=2 threads=4 \ python-path=/data/app/lib/python2.6/site-packages/ WSGIScriptAlias / /data/app/pyramid.wsgi <Directory /data/app> WSGIProcessGroup pyramid Order allow,deny Allow from all </Directory> </VirtualHost>
in /data/app/pyramid.wsgi

when I try to access domain.com in my browser, I get the error The server encountered an internal error or misconfiguration and was unable to complete your request . Here's a printout of the error log

Note that printing test in the first line of my manually added print 'test' at the top of /data/app/lib/python2.6/site-packages/pyramid-1.4-py2.6.egg/pyramid/paster.py to make sure it loads from the expected file ...
now if i run the application from pserve
$ /bin/pserve app/development.ini --reload
application started successfully, console log below
test Starting subprocess with file monitor test Starting server in PID 9132. serving on http://0.0.0.0:6543
I also tried logging into python directly to import paster.py, no problem either

Permissions
must also be accurate

What am I missing? thanks!
Edit www-data is the correct user.

Change as Graham suggested, I replaced print 'test' with paste.py with
import paste as p print p.__path__
listing when accessing the site via apache was /usr/local/lib/python2.6/dist-packages/paste , not virtualenv. I added all the examples that I could find on the Internet to point to my virtualenv in pyramid.wsgi , as well as to the pythonpath in the apache configuration file, but I still don't understand. Where else am I trying?
