How do I create a new ruby project in Eclipse indigo

Question

I have installed the following: Dynamic Languages Toolkit - Ruby Development Tools 3.0.0.v20110424-7Z--E_EkMYXO4k101442

On

Eclipse Platform Version: 3.7.2 Build id: I20110613-1736

But when I go to new projects, I see no sign of "Ruby Projects". All I have is File > New > Projects Then it opens a wizard in which I have a choice of General > Project (only)

After which it goes through the usual procedure of naming the project and voila.

I have added a new .rb file in my project and I see no interpreter kicking in for ruby either.

So for the moment eclipse looks like a very advanced notepad...

Can someone point to me what I'm missing?

Thank you
