Ruby 1.9.3 - cannot load such file for some reason

Question

Ruby 1.9.3 Very simple code and very simple question I can't deal with:

gem list --local
nokogiri (1.5.5)

gem q --local
nokogiri (1.5.5)

But a ruby script (not Rails):

require 'nokogiri'
doc = Nokogiri.XML("some valid xml....")

gives me

/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- nokogiri (LoadError)
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /home/alex/test.rb:3:in `<main>'
[Finished in 0.1s with exit code 1]

I'm aware that it's not necessary to use require 'rubygems', but even when I do that, it does not work either.

gem which nokogiri
/home/alex/.rvm/gems/ruby-1.9.3-p194/gems/nokogiri-1.5.5/lib/nokogiri.rb

What OS are you using, and how are you running ruby (e.g. rbenv?). I'm running `ruby 1.9.3p194 (2012-04-20 revision 35410)` on OS X and the above works perfectly. — djlumley, Oct 31 '12 at 11:17
That's ubuntu 12. I'm running that in Sublime text2. Other ruby scripts work perfectly, thus this issue is not because of Sublime Text. — Alan Coromano, Oct 31 '12 at 11:21
What do you mean when you say you are running this from Sublime Text? — tdgs, Oct 31 '12 at 11:34
if you're using rvm, are you sure you are installing that gem in the right gemset? If yes, are you running your script in that gemset? — Castilho, Oct 31 '12 at 11:42
I use rvm. I don't know if I installed nokogiri correctly or not. I just installed it like I always do: gem install nokogiri. How do I check that? — Alan Coromano, Oct 31 '12 at 11:46

It happens because of the wrong Sublime Text build system. The right one is here How to run ruby files in sublime-text-2

you need to add Nokogiri to the Gemfile (with the line gem 'nokogiri').

I did. This is not a Rails app. – Alan Coromano Oct 31 '12 at 11:37
bundler also exists outside rails. also check RVM gemsets – levinalex Oct 31 '12 at 11:38
-1 Should not assume Bundler is being used. Should ask in comments and then answer accordingly. – Charles Caldwell Oct 31 '12 at 12:26
Bundler is installed or not was asked in comments only. Its not visible for you Mr. @Charles Caldwell ? – vijikumar Oct 31 '12 at 12:51

I meant in the comments to the question. Not the comments to an answer that already made the assumption. – Charles Caldwell Oct 31 '12 at 12:54
