bundle exec rake spec fails to find r10k - tests wont run

[Matt Fischer]

I have a pretty plain Ubuntu 14.04 box and I usually just install the needed bundles and then exec the spec tests. This broke when r10k came along.

The issue is that r10k is not being installed where the script hard-codes to look:
/etc/puppet/modules/keystone/openstack/puppet-openstack-integration/functions: line 51: /var/lib/gems/1.9.1/bin/r10k: No such file or directory

...
Installing semantic_puppet (0.1.1)
Installing puppet_forge (2.1.3)
Installing rspec-puppet (2.2.0)
Installing puppetlabs_spec_helper (1.0.1)
Installing r10k (2.1.1)
Installing rspec-puppet-facts (1.4.1)
Installing webmock (1.24.1)
Using bundler (1.3.5)
Your bundle is complete!
Use `bundle show [gemname]` to see where a bundled gem is installed.
