本文介绍了如何在Gentoo Linux上安装Ruby 1.9.2版本，并解决了大部分Ruby应用仍基于Ruby 1.8的问题。通过配置Portage设置并手动指定Ruby 19为目标版本，同时指定了特定版本的RubyGems以确保兼容性。
Ruby1.9.2 have released,but it's annoying on Gentoo,cause most ruby apps are based on ruby 1.8.
First ,installing ruby19 is easy,add some options in portage configure files.
[quote]RUBY_TARGETS="ruby19"[/quote]in /etc/make.conf
[quote]echo "dev-lang/ruby" >>/etc/portage/package.keywords[/quote],cause ruby19 is masked in Gentoo(from this,the ruby are not supported as good as python:)
Then the rubygems,it's really hard,from mine,rubygems 1.3.7 just support ruby18,jruby.and i found out that the rubygem 1.3.7-r4 support ruby19,so just do like this:
[quote] emerge "=rubygems-1.3.7-r4"[/quote]
