Setup Diaspora on Ubuntu

> sudo apt-get install mongodb-stable

Unless you're doing this on your desktop - don't do that, the package in mongodb repos has broken dependencies and incorrectly depend on xulrunner-dev instead of xulrunner. This will install about 200MiB of completely unnecessary development packages and X11 stuff on your box which is not something you'd want for a headless server.

Also, I'd suggest using rvm instead of apt-packaged ruby & gems, because otherwise you'd have to `sudo gem install bundler && sudo bundle install`, and I doubt you really want to make your ubuntu more slackware-ish. ;)

I did something like this (partially writing from memory):

  bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
  rvm install 1.8.7
  rvm use 1.8.7@diaspora --create
  gem install bundler
  cd diaspora*
  bundle install
