.htaccess problem

[eluser]musonic[/eluser]
I've followed the tutorial here to the letter, but I cannot get it to work. Is there anything else I should check?
I'm using Mac OS X 10.6 with the bundled Apache setup. I'm trying to get this working on localhost.

SOLVED:

I added a directory to my httpd.conf file that specifically targeted the project I was looking at. Seems to work, but not a very satisfactory solution if I have more than one site in my web root.
