Locking mongo gem to specific version

[cjhubert]

It seems like after an update to the mongo ruby gem, unable to run the recipe successfully on Ubuntu 12.04. Just am getting:

================================================================================       
Error executing action `install` on resource 'chef_gem[mongo]'

This change just locks it to a specific version that works, though ideally we'd want to eventually figure out why the change broke the cookbook.

It seems like the same solution that applied to the PHP mongo driver applies here, if I run sudo apt-get install libsasl2-dev it fixes it. Not sure how we solve this in the cookbook, though.

Because chef_gem is run in the compile phase, that dependency must also be satisfied in the compile phase. For the moment I'm using this hacky approach:

package 'libsasl2-dev' do
  action :nothing
end.run_action(:install)

[cjhubert]

Interesting, with my changes I was able to kitchen converge the ubuntu 12.04 boxes. Are you running on a different platform? What error were you getting?

Right, I understand now that he means that instead of my change. I'm fine with that change instead, just not sure how to go about actually fixing this. Maybe logging a bug in mongo's jira to at least let them know about it?

@ceejh: Looks like csasl is now core to the ruby driver, so we'll probably just have to live with this. See https://github.com/mongodb/mongo-ruby-driver/pull/459

You want to use this in the PR, or shall I submit one? (you get the credit here for raising this - thanks!)

[cjhubert]

Feel free to submit it as a separate PR and I'll close this one, thanks for doing the research into it.
