The homebrew node recipe now (beginning with 0.8.0) comes with npm.
It appears you already have npm installed at #{modules_folder}/npm.
To use the npm that comes with this recipe,
first uninstall npm with `npm uninstall npm -g`.
Then run this command again.
If you would like to keep your installation of npm instead of
using the one provided with homebrew,
install the formula with the --without-npm option added.

Homebrew has NOT installed npm. We recommend the following method of
installation:
curl https://npmjs.org/install.sh | sh
After installing, add the following path to your NODE_PATH environment
variable to have npm libraries picked up:
#{modules_folder}

Homebrew installed npm.
We recommend prepending the following path to your PATH environment
variable to have npm-installed binaries picked up:
