Hi Stefan,

Thanks a lot for your help. It was kinda fuzzy in my head, but
because you fortified my sight of the problem, I get nearer to it. In the
fact /usr/local/lib/site_ruby is created by the rubygems install script,
so it's fine for me (I think).

The real problem is that I installed some gems like `og`, but irb can't
find the include path to use it :

irb(main):001:0> require 'og'
LoadError: No such file to load -- og
        from (irb):1:in `require'
        from (irb):1


irb(main):001:0> require_gem 'og'
NoMethodError: undefined method `require_gem' for main:Object
        from (irb):1

It looks like gem has some problems.
I had to compile it from souce (latest from rubyforge) because ubuntu
doesn't have the gem package. Here are the compile options, it looks all
right for me, but maybe I missed something :

ruby setup.rb show
prefix               /usr
bindir               $prefix/bin
libdir               $prefix/lib
datadir              $prefix/share
mandir               $prefix/share/man
sysconfdir           /etc
stdruby              $libdir/ruby/1.8
siteruby             $prefix/local/lib/site_ruby
siterubyver          $siteruby/1.8
siterubyverarch      $siterubyver/i386-linux
rbdir                $siterubyver
sodir                $siterubyverarch
rubypath             /usr/bin/ruby1.8
rubyprog             /usr/bin/ruby1.8
makeprog             make
shebang              ruby
without-ext          no

I did `sudo ruby setup.rb all` to install it.

I guess I'm not really good at describing the problems.. The subject would
more be like : rubygems not working with ubuntu's ruby package.

Thanks again and have a nice day,
