Use macports to install mongodb

sudo port install mongodb

Chown db dirs to _mongo user

sudo chown -R _mongo:_mongo /opt/local/var/db/mongodb/ sudo chown -R _mongo:_mongo /opt/local/var/log/mongodb/

Copy launchagent and load it

sudo cp /opt/local/etc/LaunchDaemons/org.macports.mongodb/org.macports.mongodb.plist /Library/LaunchAgents/ sudo launchctl load -w /Library/LaunchAgents/org.macports.mongodb.plist

f.each do |i|
  i.call
