Video Tutorial on Setting up LabelMe with Ubuntu 12.04

I made a video tutorial for me and those who are not familiar with Apache configurations on Ubuntu.

Hope this helps.

It might be better if the authors could specify how to do the following two steps in detail, it took me a while to figure that out.
- Enable authconfig in Apache so that server side includes (SSI) will work. This will allow SVG drawing capabilities. This is the most common source of errors, so make sure this step is working.
- Allow perl/CGI scripts to run. This is the second most common source of errors.

Start by reviewing the linked video tutorial and the existing setup documentation, if present. Document the Ubuntu 12.04 Apache steps for enabling SSI/authconfig and allowing Perl/CGI scripts to run; done when both common configuration errors are explained clearly for new LabelMe users.
