[Problema] Instalação do Rails

This message was edited 1 time. Last update was at 03/05/2010 15:39:10

Pessoal,

Me interessei por ruby apartir da apostila da caelum que foi liberada a pouco.
Estou tentando partir pra utilizar Rails e estou tentando fazer a instalação do mesmo.
Utilizo o ubuntu, e aqui no trabalho tem um proxy que está bloqueando quase tudo pelas instalações via "apt-get" e o "gem install rails" está dando um probleminha que eu não sei qual é.

Problema ao utilizar "gem install rails":

/usr/local/lib/ruby/site_ruby/1.9.1/rubygems/package.rb:10:in `require': no such file to load -- zlib (LoadError)
	from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/package.rb:10:in `<top (required)>'
	from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/format.rb:9:in `require'
	from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/format.rb:9:in `<top (required)>'
	from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:10:in `require'

	from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/dependency_installer.rb:3:in `<top (required)>'
	from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/commands/install_command.rb:4:in `require'
	from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/commands/install_command.rb:4:in `<top (required)>'

	from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/command_manager.rb:161:in `load_and_instantiate'
	from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/command_manager.rb:90:in `[]'
	from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/command_manager.rb:146:in `find_command'

	from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems/gem_runner.rb:58:in `run'
	from /usr/local/bin/gem:21:in `<main>'

por isso estou realizando as instalações pelo source dos projetos.
Sou um iniciante no Linux também, porém depois de algumas batalhas pra compilar e instalar o Ruby, eu consegui.
Agora estou penando pra conseguir o utilizar o rails e não consigo pois também não achei nenhum conteúdo na internet que me ajudasse com isso.
No source-forge do projeto (http://rubyforge.org/frs/?group_id=307) fiz o download do source do rails e descompactei, eis a seguinte estrutura de pastas:

E agora? O que faço apartir daqui? estagnei

Solução para o problema acima: instalar todas as dependecias do rails na mão. -> http://rubyforge.org/

Ao criar um projeto: "rails teste" é me gerado uma estrutura de diretórios...
Quando vou executar o servidor pelo comando "ruby script/server" me é dado o seguinte erro:
