Hello,

bundle install this is the error that i get. I guess its not finding
the files

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native
extension.

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:

  --without-opt-include=${opt-dir}/include

libbz2 not found, maybe try manually specifying --with-bz2-dir to find
it?

Gem files will remain installed in
/home/taka/.rvm/gems/ruby-1.9.3-p194/gems/bzip2-ruby-0.2.7 for
inspection.
Results logged to

An error occurred while installing bzip2-ruby (0.2.7), and Bundler
cannot continue.
Make sure that `gem install bzip2-ruby -v '0.2.7'` succeeds before
bundling.

You need to install the BZ compression library, including it's header files,
usually in libbz2-dev or libbz2-devel.
