mod_wsgi getting permission denied writing webapp/info.log

I've followed all instructions for installing graphite at http://readthedocs.org/docs/graphite/en/latest/install.html.

Machine: Ubuntu 11.10 Server x64

Ran all the installation scripts using sudo.

Got Apache2 running with the graphite vhost file that was under the examples directory.

Defined "graphite" in my DNS to point to the machine hosting Apache2 & graphite.

When I hit http://graphite I get a 500 error in browser and the following in /opt/graphite/storage/log/webapp/error.log:

When I check the permissions for /opt/graphite/storage/log/webapp/ it's root:root all the way up the tree. My question is should this directory where info.log is going to be written belong to the user/group that apache2 runs under? In Ubuntu's case it's www-data.

Did I make a mistake by running all the pkgs installation scripts using sudo?

Anyways, any help would be much appreciated.

Thanks in advance.
