$> tar zxvf rubygems-1.3.7.tgz
$> cd rubygems-1.3.7
$> sudo ruby setup.rb

この状態では zlib でエラーが出る

$> gem update --system
ERROR:  Loading command: update (LoadError)
no such file to load -- zlib
ERROR:  While executing gem ... (NameError)
uninitialized constant Gem::Commands::UpdateCommand

$> sudo yum install zlib-devel
$> cd ruby-1.8.7-p302/ext/zlib
$> ruby extconf.rb
$> make
$> sudo make install

完了

$> gem env
