If this is your first install, automatically load on login with:
    cp #{prefix}/org.mongodb.mongod.plist ~/Library/LaunchAgents
    launchctl load -w ~/Library/LaunchAgents/org.mongodb.mongod.plist

If this is an upgrade and you already have the org.mongodb.mongod.plist loaded:
    launchctl unload -w ~/Library/LaunchAgents/org.mongodb.mongod.plist
    cp #{prefix}/org.mongodb.mongod.plist ~/Library/LaunchAgents
    launchctl load -w ~/Library/LaunchAgents/org.mongodb.mongod.plist

Or start it manually:
    mongod run --config #{prefix}/mongod.conf
