Bundler cannot find rake but it seems installed

I am having some struggles with bundler and rake. According to the error message, bundler can't find rake-10.3.1. Here's the thing, everything I've done seems to indicate that rake-10.3.1 is installed. I've been floating in the google-sphere for days without finding a solution that resolves this issue for me.

I'm on Mac OSX 10.8.5. Ruby version is 1.9.3-p392.

Error:

bundle exec rspec spec/bdr_pre_dev_spec.rb

Here are things I've done:

Blasted away the Gemfile.lock and tried a bundle install. This reinstalls gems and clearly shows rake-10.3.1 being installed but when I run rspec it still says it can't find rake.
Manually try to install gem with gem install rake -v 10.3.1 which also indicates that rake-10.3.1 is installed but rspec command still throws the same error.
Explicitly specified rake 10.3.1 in the Gemfile, blasted away Gemfile.lock and bundle install
Uninstall rake (all versions found) gem uninstall rake and reinstall rake using gem install rake -v 10.3.1
Uninstalled the version of ruby I was using and reinstalled it with rvm uninstall ruby-1.9.3-p392 and then rvm install ruby-1.9.3-p392.
Downgrade bundler to 1.6.1
Uninstall and reinstall bundler
rvm implode and reinstall rvm

None of these fixed the issue.

bundle show says that rake-10.3.1 is installed.

unset RBXOPT

So, I finally managed to get this error to go away. I started thinking it was some weird permission issue.

To solve this problem, I did the following:

Open the Disk Utility, Applications/Utilities/Disk Utility
Repair Permissions
Remove the .bundle directory in my project
Remove the vendor directory in my project
Remove the Gemfile.lock
bundle install

After that it started working without complaining about not finding rake. Crazy, man. Ugh. Hopefully this helps other folks if they run into the same issue.
