$ ./nodebb setup

Is there someone who has done a dreamhost install who can explain to me what you have to do differently for dreeamhost?

I get errors when trying to install mongodb, and I can't tell you if npm is installed... though it's supposed to be. In dreamhost I have it selected along with nodeJS in the initial setup.
