CentOSのRails3環境で、「opensslが読み込めん!」と怒られたら?

どんな例外を吐く?

[twitter@centos twitter_trend]$ ./script/rails server

参考ページに寄れば

rvm pkg install openssl
rvm remove 1.9.2
rvm install 1.9.2 --with-openssl-dir=$HOME/.rvm/usr


なぬ? opensslはオレオレビルドにして、

それをリンクするようにrubyをビルドしなおせだと?

やってみた

うまく動くか、wktkするー

動かしてみた

[twitter@centos twitter_trend]$ ./script/rails server

Oops!

気を取り直して

[twitter@centos twitter_trend]$ rvm use 1.9.2 --default

動いたー!

でも、ここに辿りつく前までに、rubygemsを入れるためだけにrubyをオレオレビルドしたり、
rvmを入れるためだけにgitをオレオレビルドしたり、CentOS 5.xは古すぎて身体に良くないですw
