The current steps outline how to compile the package yourself, however, they do now have a version for the raspberry pi, well, up to 0.10.26 anyway.

So might be worth changing the Debian NodeJS section with

wget http://nodejs.org/dist/v0.10.26/node-v0.10.26-linux-arm-pi.tar.gz tar -xvzf node-v0.10.26-linux-arm-pi.tar.gz node-v0.10.26-linux-arm-pi/bin/node --version

You should see: v0.10.26

NODE_JS_HOME=/home/pi/node-v0.10.26-linux-arm-pi PATH=$PATH:$NODE_JS_HOME/bin npm —version

You should see: 1.4.3

Not sure if this helps or not.. đŸ˜†
