greenstone...ALMOST THERE!

I feel like I am SO CLOSE to having greenstone up and running on my mac.

As near as I can tell, the only thing I still need to do is add the following directive to the httpd.conf file:

ScriptAlias /gsdl/cgi-bin "/opt/greenstone/cgi-bin"

Options None
AllowOverride None


Alias /gsdl "/opt/greenstone"

Options Indexes MultiViews FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all



So here's my question...where is the httpd.conf file, and how do I add this directive to it? Help!
