[Radiant] please help: How do I set the default URL path with multiple installs?

Hi,

I've managed to set two radiant sites using apache 1.3 and fcgi. Now I can
access them site at http://www.mydomain.org/radiant1 and
http://www.mydomain.org/radiant2

However, I can't navigate the sites because all the links are generated
using the default path /

So if I click the News section for example, the site refers me to
http://www.mydomain.org/news instead of
http://www.mydomain.org/radiant1/news.

Where do I set the default url path for each of my radiant sites?

Jose.
