Ruby on rails legacy application error with linecache gem [duplicate]

Question

I have ruby on rails legacy application and I have the following error when I run the application

/usr/local/lib/ruby/gems/1.9.1/gems/linecache19-0.5.12/lib/trace_nums19.so: undefined symbol: ruby_current_thread - /usr/local/lib/ruby/gems/1.9.1/gems/linecache19-0.5.12/lib/trace_nums19.so (LoadError)
  /usr/local/lib/ruby/gems/1.9.1/gems/linecache19-0.5.12/lib/tracelines19.rb:12:in `require'
  /usr/local/lib/ruby/gems/1.9.1/gems/linecache19-0.5.12/lib/tracelines19.rb:12:in `rescue in <module:TraceLineNumbers>'

Full error can be found Here

Could anyone help me spot the problem?

I appreciate the effort to relate to possible duplicates. I am looking for a solution I already stumbled upon them and they did not work. @DamienRoche The link to ruby source is dead in that post. — Pavan K

linecache has a patched gem to work with ruby-debug

add this to your Gemfile

gem 'linecache19-patched' instead of 
gem  'linecache19'
