[news.eclipse.technology.dltk] dltk 1.0 ruby support howto?

[kittekat@xxxxxxxx (Wolfgang Kittenberger)]

I wanted to test the new dltk 1.0 & ruby IDE. I learned that this will be 
supported on Galileo, so I downloaded "eclipse-SDK-3.5-macosx-cocoa.tar", 
expanded it and tried to install dltk as I did it under Ganymed via the 
update site: http://download.eclipse.org/technology/dltk/updates/. But 
there 1.0 is not offered, only five different 0.9x versions.

Then I downloaded from 
http://download.eclipse.org/technology/dltk/downloads/drops/R1.0/R-1.0-200906171219/ 
the dltk core and the ruby IDE, and moved the content of the features and 
plugins directories in the eclipse 3.5 directory.

I can see the wanted features and plugins in the "Installation Details" of 
the "About" menu, but I do NOT see in the "Preferences" the "Ruby" menu 
item to configure my interpreter,... So it seems that I cant use the Ruby 
IDE of DLTK 1.0

What did I wrong???  

here the dltk related info from the "configuration":
