RubyGems 1.3.6 のインストール

昨日（ Ruby 1.8.7インストール - tetu1984の日記）の続き

インストール

ソースをとってきて、インストール。

$ wget http://rubyforge.org/frs/download.php/69365/rubygems-1.3.6.tgz
$ tar zxf rubygems-1.3.6.tgz
$ cd rubygems-1.3.6
$ sudo ruby setup.rb install

確認

$ gem --version
1.3.6

さっそく使ってみる・・・

が、しかし

$ gem list

どうやら、zlibをロードできなくて、怒られているみたい。
zlib-develをいれた後に、Rubyがそのライブラリを使えるように、該当する部分をコンパイルしてあげれば良いという感じ。
※ 以下の ~/install/ruby-1.8.7-p249/ は、Rubyをインストールした時のディレクトリ

$ sudo yum install zlib-devel
$ cd ~/install/ruby-1.8.7-p249/ext/zlib/
$ ruby extconf.rb
$ make
$ sudo make install

再度試みる

$ gem list
