'npm install' doesn't work

'npm install' doesn't currently work for me:

➜  presentz.org git:(master) ✗ npm install

It succeeds when I change package.json to depend on slideshare 0.1.1, though of course that version might not have some changes presentz.org depends on. Added paulohp/node-slideshare#5 for a new upstream release.
