UPDATE: this was fixed after Meteor v0.4 (2012). For historical purposes:
Excerpt from du

The commands that work for me are:
sudo service mongod stop
mongod --noprealloc --smallfiles
If you are getting “ERROR: dbpath (/data/db) does not exist.” when running 2,
then run these commands before 2.
sudo mkdir -p /data/db/
sudo chown `id -u` /data/db
