Could not require "perftools"

[sevos]

Hey,

I cannot require "perftools", I added perftools.rb to my Gemfile, bundle install ran without errors, but now I am getting following errors:

irb(main):002:0> require 'perftools'LoadError: cannot load such file -- perftools        from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
        from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
        from (irb):2        from /usr/bin/irb:12:in `<main>'

I also does not load with Bundler.setup. My code using PerfTools is raising: uninitialized constant PerfTools.

Ruby 2.0.0-p0, Ubuntu 13.04. I tried master branch and packaged gem in newest version as of this writing.

I inspected the place, where gem is installed and instead of lib directory I have an executable binary file with 473 kilobytes in size. Executing this file causes segmentation fault.

For all that come across this... You're probably missing this line in your

./environments/test.rb

config.middleware.use ::Rack::PerftoolsProfiler, :default_printer => 'gif'

This should probably be marked as closed.
