problems trying to "make" it

[Alexandre Almeida]

Hi!
I'm new here. My name is Alexandre and this is my first post.

o follow the steps to add gtk2 interface.
I downloaded the ruby-gtk2 on http://ruby-gnome2.sourceforge.jp to the root=
folder (I use Suse linux). Then, I typed "ruby extconf.rb" ... :
