あるRailsプロジェクトでbundle installした際に下記のエラが発生したので、その対応について対策を書いておきます。

An error occured while installing linecache19 (0.5.12), and Bundler cannot continue.
Make sure that `gem install linecache19 -v '0.5.12'` succeeds before bundling.
ruby-debug19をいれようとした際に、vm_core.hが見つからずに発生してしまっているようです。
rubyのソースの場所を指定します。私の場合はrvm経由でいれているので下記の通りになります。
$ gem install ruby-debug19 -- --with-ruby-include=\$rvm_path/src/ruby-1.9.3-head/
