The error is in the mkmf.log file. That file should be located at /home/hxh/.rvm/gems/ruby-1.9.3-p448/gems/linecache-0.46/ext/linecache/mkmf.log.

If not, you can use

sudo find / -name mkmf.log

to find it.

Ended up solving my problem by installing the gem debugger instead: http://rubygems.org/gems/debugger

• Add the gem to your Gemfile: gem 'debugger', group: [:development, :test]
• Run bundler: bundle install

If you need some guidance on how use the gem follow the video tutorial Creating a blog in 15 minutes with Rails - Part 2. Basically, you need to do two things to interrupt the server rendering a page.

• Add the command debugger somewhere in your ruby code. If its a view use <% debugger %> instead.
• Start the server with a parameter: rails server --debugger

gem install ruby-debug19 - *** extconf.rb failed ***

ruby-debug19 only works on Ruby 1.9. For Ruby 2.0 and above use byebug.

gem install byebug

brew install cmake

Or you can install it from the source following these instructions.
