In the "Work With" field copy/paste http://download.eclipse.org/
Then you must do the same thing except with http://dpp.sourceforge.net/
Problem seems to be that the original install script for Saros tried referring to a link that no longer exists. If you install the dependency beforehand though from the first link everything works just fine.
Now to set up Saros you go to Saros and then start the configuration. Input your gmail and password AND NOW expand the window downward and press the server button. Put gmail.com in there. Then configure it as you wish. (I would set it to auto connect).
