Rails3.1の古い案件の修正が入ったので、環境を構築していたのですが、Nokogiriが1.5.2を入れないと動かない構成でして、苦労しましたのでメモしておきます。

解決方法
NokogiriとUbuntuで下記のもので入るようになるとはあるのですが、1.5.2はこれでもうまく行かず。。

sudo apt-get install libxml2-dev libxslt1-dev |
下記のオプションをつけてなんとかインストールできました。

sudo gem install nokogiri -v '1.5.2' -- --with-cflags="-O2 -pipe -march=native -w" |
