$ sudo wget http://rubyforge.org/frs/download.php/56227/rubygems-1.3.3.tgz
$ tar -xvzf rubygems-1.3.3.tgz
$ cd rubygems-1.3.3
$ sudo ruby setup.rb
$ gem -v

ruby script/server
报错：`require_frameworks': no such file to load -- net/https (RuntimeError)
原来是缺少 libopenssl-ruby library:
解决方案:
$sudo apt-get install libopenssl-ruby
再次运行ruby script/server
