Bundler has been giving me these errors (across completely different repos) for a while now and I really need to figure out what's causing this. Anybody have a clue?

Bundler gave the error "Could not find rake-10.1.0 in any of the sources" while processing "/Users/olivierlacan/Development/envylabs/codeschool/iOS7Course/Gemfile". Perhaps you forgot to run "bundle install"?
Bundler gave the error "Could not find libv8-3.11.8.13 in any of the sources" while processing "/Users/olivierlacan/Development/envylabs/codeschool/TryDevTools/Gemfile". Perhaps you forgot to run "bundle install"?
Bundler gave the error "Could not find gem 'jquery-rails (~> 2.0.1) ruby' in the gems available on this machine." while processing "/Users/olivierlacan/Development/envylabs/codeschool/BackboneCourse/Gemfile". Perhaps you forgot to run "bundle install"?
Bundler gave the error "Could not find libv8-3.11.8.17 in any of the sources" while processing "/Users/olivierlacan/Development/envylabs/codeschool/FrontEndFormationsCourse/Gemfile". Perhaps you forgot to run "bundle install"?
Bundler gave the error "Could not find libv8-3.11.8.13 in any of the sources" while processing "/Users/olivierlacan/Development/envylabs/codeschool/NodeJSCourse/Gemfile". Perhaps you forgot to run "bundle install"?

Does it come up when you use 1.5.0.rc.2? (i'm thinking concurrency bug) 1.3.5?

This started happening to me after I had uninstalled a ruby version via rbenv and reinstalled. All projects using that ruby version were mentioned in the error until I did a bundle install in each of those projects.

@stringsn88keys you are my hero. This was so annoying.
