Rubyのインストールとか

前にも書いた気がするけど、RubyをRVMでインストールしたりとか。あと今回はbundler使ってみたりとか。
環境：Ubuntu 11.04 32bit

いろいろインストール

$ sudo apt-get install -y libruby1.9.1  # 要らないかも
$ bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
$ cat <<'EOB' >> ~/.bashrc
# rvm
RVM=$HOME/.rvm/scripts/rvm
if test -f "$RVM"
then
  source "$RVM"
fi
EOB
$ rvm package install iconv
$ rvm package install openssl
$ rvm package install readline
$ rvm package install zlib
$ rvm install 1.9.1 -C --with-iconv-dir=$HOME/.rvm/usr --with-openssl-dir=$HOME/.rvm/usr --with-readline-dir=$HOME/.rvm/usr --with-zlib-dir=$HOME/.rvm/usr
$ rvm use 1.9.1
$ echo 'gem: --no-ri --no-rdoc' > ~/.gemrc
$ gem install bundler

bundlerを使ってみる

$ mkdir project
$ cd project
$ cat <<'EOB' > Gemfile
source "http://rubygems.org/"
gem "padrino"
EOB
$ bundle install --path vendor/gems

で、実行すると

ちょっと何言ってるかわかんないです(>_<)
検索してみると1.9.2ではエラーが出ないらしいので1.9.2で試してみた。

Ruby1.9.2でインストール

$ rvm install 1.9.2 -C --with-iconv-dir=$HOME/.rvm/usr --with-openssl-dir=$HOME/.rvm/usr --with-readline-dir=$HOME/.rvm/usr --with-zlib-dir=$HOME/.rvm/usr
$ rvm use 1.9.2
$ gem install bundler
$ bundler install --path vendor/gems

え、なにそれ。回避方法が1.9.1を使わない、だなんて……
まあいい…かな？
