$ brew upgrade node

==> ./configure --prefix=/usr/local/Cellar/node/0.8.0 --without-npm
==> make install
==> Caveats
Homebrew has NOT installed npm. We recommend the following method of
installation:
  curl http://npmjs.org/install.sh | sh

After installing, add the following path to your NODE_PATH environment
variable to have npm libraries picked up:
  /usr/local/lib/node_modules
