Eclipse install problem windows 2000 or XP

Hello,

Once more, an installation problem.
Having previously installed Ruby 1.6.8-8 (from http://rubyinstaller.sourceforge.net/ complete install with some packages) :
I installed Eclipse 2.1 (eclipse-platform-2.1-win32.zip on Windows XP or Windows 2000, Pentium IV, sun jre 1.4.2-01), then Ruby Eclipse 0.3.2.
Never found the “Installed interpreters” node in the tree (Windows/Preferences menu, under “Ruby” there is only the node “Editor”). Tried to find something related to Ruby in the different perspectives… Unsuccessfull.

I have tried running eclipse before or after installing the ruby plugin ; and restarting the computer as well.
I have tried with jdk 1.3.1 (called through “eclipse.exe -vm …\javaw.exe”).
After creating a new ruby project with a file, the file properties shows only its location, size and attributes.
Really nothing.

Is there some hope of having this working without recompiling from sources ? Where’s the problem ? Thank you for any hint.
