title: Meteor.js mongodb version
body: <p>This may be a dumb question, but I am confused about something. I have downloaded mongodb 2.6.4(latest) version to my mac, and deleted old mongodb folder which had executables and other stuff. But whenever I execute 'meteor mongo' command from my meteor.js application, it is opening MongoDB shell version 2.4.9, not the latest one. Why is this happening? Where is this old version is coming from? How can I use the latest version in meteor.js application?
  Thank you</p>
