Could not find rake-10.1.0 in any of the sources

I've got a ruby on rails application (gitlab) which is installed via puppet.

Everything on the test system runs fine, but production generates an error about rake

Running /home/git/gitlab-shell/bin/check
Could not find rake-10.1.0 in any of the sources
Run bundle install to install missing gems.

Here is the full rake check:

root@gitlab:/home/git# sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

  Try fixing it:

The step 'gitlab-shell check' effectively runs the following command. If I run that command manually, everything passes.

root@gitlab:/home/git/gitlab# sudo -u git -H /home/git/gitlab-shell/bin/check 
Check GitLab API access: OK
Check directories and files: 
    /home/git/repositories: OK
    /home/git/.ssh/authorized_keys: OK

I have verified that rake is in fact installed

 root@gitlab:/home/git/gitlab# gem install rake -v 10.1.0
 root@gitlab:/home/git/gitlab# bundle install

 root@gitlab:/home/git/gitlab# sudo -u git -H gem install rake -v 10.1.0
 root@gitlab:/home/git/gitlab# sudo -u git -H bundle install

Ruby is installed with update alternatives

 root@gitlab:/home/git/gitlab# sudo -u git -H ruby --version
 ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]
 root@gitlab:/home/git/gitlab# sudo -u git -H ls -l `which ruby`
 lrwxrwxrwx 1 root root 22 Oct  8 20:26 /usr/bin/ruby -> /etc/alternatives/ruby

 root@gitlab:/home/git/gitlab# sudo -u git -H gem --version
 2.1.10
 root@gitlab:/home/git/gitlab# sudo -u git -H ls -l `which gem`
 lrwxrwxrwx 1 root root 21 Oct 10 20:50 /usr/bin/gem -> /etc/alternatives/gem

I've tried the solution mentioned below, to allow shared gems

I've exhausted google, so I'm hoping for someone more familiar with ruby to offer any ideas how to resolve the error. Could not find rake-10.1.0 in any of the sources
