how to install kross for ruby on ubuntu

[Bram Kuijper]

Hi all,

does anyone know of any pointers towards more information on how to 
install the kross KDE-scripting modules for ruby?

I can find some tutorials on how to _use_ kross, but information on how 
to get the corresponding ruby modules installed is extremely sparse.

One thing I know is that I need to have kdelibs4 installed, but any 
information beyond that would be appreciated.

thanks,
Bram
