Answer 1

I've just done a download of the latest official release from here:
https://github.com/TryGhost/Ghost/releases
Then I've run npm install --production and the only warning I get is this:
npm WARN engine html-to-text#0.1.0: wanted: {"node":"~0.8.0"} (current: {"node":"0.10.30","npm":"1.4.23"})
Are you sure you've downloaded the latest release version and not the github repository instead or another version?
Try to install ghost from that link in a clean directory, without sudo and see if it's still giving you warning.

Answer 2

sudo npm cache clean -f
sudo npm install -g n
sudo n stable
//This will install the latest stable version or you can go to https://nodejs.org for the latest 'recommended for most users' version and use:
sudo n 4.6.0
