I've prepared an initial port of 3.1RC1, if you are interested.  I 
haven't downloaded the Linux package yet to compare file locations, but 
at first glance the help contents appear to display correctly after 
configuring an external browser.

The port files are here:

  http://www.varju.ca/alex/freebsd/eclipse-devel-3.1RC1-1.tgz

I'll probably submit a PR for this in the next day or two.

Alex.

------ADD something interest-- changed the browser to  
/usr/X11R6/bin/mozilla
     and I got the welcome page working BUT still no help

The browser was launched and returns the usual error report:

"The document that you have requested is not available. The link may be 
wrong, 
or you may not have the corresponding product feature installed."

However I get this error message from the eclipse platform error log:
