error Installing linecache19 gem bundler rvm - ruby

Question

I'm failing to install linecache19 gem via bundler with an rvm installation of ruby 1.9.2 on aptosid (ie debian sid).
I am new to ruby but my ruby installation is clearly not completely mis-configured as I have been able to install rails and a bunch of gems.
The output I get is the following:
Installing linecache19 (0.5.12) with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
/home/caz/.rvm/rubies/ruby-1.9.2-p320/bin/ruby extconf.rb
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
Provided configuration options:

Gem files will remain installed in /home/caz/.rvm/gems/ruby-1.9.2-p320/gems/linecache19-0.5.12 for inspection.
Results logged to /home/caz/.rvm/gems/ruby-1.9.2-p320/gems/linecache19-0.5.12/ext/trace_nums/gem_make.out
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.
I have tried the solution which is usually suggested:
gem install ruby-debug19 -- --with-ruby-include=$rvm_path/src/ruby-1.9.2-p320
I have also tried using the --force option without success as per the following:
Installing Gems without rvm, as root, with explicit version of ruby
I'm confused by the presence of "1.9.1" in the path reported in the output- I wonder whether this is a hangover of the debian ruby package and the source of my problems.
ps this is all in aid of installing the Smallest Federated Wiki. I encourage readers to take a look at this project.

Answer 1

in your terminal enter rvm requirements
It will provide you with something like
Additional Dependencies:
# For Ruby / Ruby HEAD (MRI, Rubinius, & REE), install the following:
ruby: /usr/bin/apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion
go ahead and copy the command and run it. It will install all dependencies required for running ruby.
