icleave,
Are you running the Selenium core? You need to have Selenium running before you can use the Selenium Remote-Control (driven by WWW::Selenium. It should be along the lines of (from memory and likely off a bit):
java --jar selenium-core.jar

You can verify that you have something listening on port 4444 by doing a netstat -an | grep LISTEN | grep 4444. If you don't see anything then you haven't properly started Selenium.
