I added ``` gem 'pry-stack_explorer' ``` to my Rails project's Gemfile, and now when doing `rails console`, I get the following: ``` macbuech:tttt josh$ rails c Loading development environment (Rails 3.2.5) dyld: lazy symbol binding failed: Symbol not found: _rb_vm_make_env_object Referenced from: /Users/josh/.rvm/gems/ruby-1.9.3-p0@tttt/gems/binding_of_caller-0.6.7/lib/binding_of_caller.bundle Expected in: flat namespace dyld: Symbol not found: _rb_vm_make_env_object Referenced from: /Users/josh/.rvm/gems/ruby-1.9.3-p0@tttt/gems/binding_of_caller-0.6.7/lib/binding_of_caller.bundle Expected in: flat namespace Trace/BPT trap: 5 ```
