Error installing linecache19

Question

I've been trying to run bundle install. What follows is a series of commands I entered and the relevant snippets of the error messages.

bundle update

An error occurred while installing linecache (0.46), and Bundler cannot continue.
Make sure that gem install linecache -v '0.46' succeeds before bundling.

gem install linecache -v '0.46'

Can't handle 1.9.x yet

gem install linecache19

checking for vm_core.h... no

and finally:

gem install linecache19 -- --with-ruby-include=/opt/t/rvm/src/ruby-1.9.3-p194

ERROR:  Error installing linecache19:

force the Gemfile to use these version

gem 'linecache19', '0.5.13', :path => "~/.rvm/gems/ruby-1.9.3-p0/gems/linecache19-0.5.13/"

and then bundle install
