I recently tried installing MongoDB on my Mac using Homebrew. I did it exactly like t's described here: http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/

I'm aware of the fact that you're usually not providing support for a pre-release version, but I'm sure that fixing a bug before many other people will experience it, is a great thing to do.

On the first try of executing the command, I get a different error than on the second and on all other attempts. I've attached a screenshot of both errors.

Oh, I forgot to say that as soon as I execute the install-command, my mac's fan also starts turning really fast (without performance issues). As the installation finishes with an error, it just stops.
