Slackware, ruby, rubygems and rubygames.
 

I try to do a clean install of rubygame on Slackware 12.1.

First, how do i install rubygems ?

Unzipping the archive and run ruby setup.rb is enough ?
Maybe i have to specify some path ?

Yes, as root.

Ok, done !

Now i typed :

gem install rake

then :

gem install rubygame

Building native extensions. This could take a while...

When i launch this :

1 #! /usr/bin/ruby -w
2
3 require ‘rubygame‘
4
5 Rubygame.init
6 screen = Rubygame::Screen.new [640, 400]
7 loop {}
8

I got this :

bash-3.1$ ruby rubytest.rb
rubytest.rb:3: syntax error, unexpected tIDENTIFIER, expecting $end
3 require ‘rubygame‘
^
bash-3.1$

What have i done wrong ?

Mmm, no idea. What does that:
gem_make.out say?

I need glasses...
