/tmp/build_3srt9ifqtbs6m/vendor/bundle/ruby/1.9.1/gems/therubyracer-0.11.0/ext/v8/build.rb:42:in `build_with_system_libv8': unable to locate libv8. Please see output for details (RuntimeError)
from extconf.rb:22:in `<main>'
The Ruby Racer requires libv8 ~> 3.11.8
to be present on your system in order to compile
and link, but it could not be found.
In order to resolve this, you will either need to manually
install an appropriate libv8 and make sure that this
build process can find it. If you install it into the
standard system path, then it should just be picked up
automatically. Otherwise, you'll have to pass some extra
flags to the build process as a hint.
If you don't want to bother with all that, there is a
rubygem that will do all this for you. You can add
following line to your Gemfile:
gem 'libv8', '~> 3.11.8'
We hope that helps, and we apologize, but now we have
to push the eject button on this install.
thanks,
The Mgmt.

確かに最新です、私はちょうど今それらを再インストールしました。
どうすれば修正できますか?
PS Ubuntu 12.1、x64。
