Spork + Rspec = Network is unreachable

[Mrugesh Karnik]

Hi,

I'm following http://ruby.railstutorial.org/chapters/static-pages#sec:guard.
The setup works fine on one of my machines, but on another I get this:

Guard uses Libnotify to send notifications.
Guard is now watching at '/home/mrugesh/git/rails/sample_app'
Starting Spork for RSpec
ERROR: Guard::Spork failed to achieve its <start>, exception was:

Checking with netstat and running rspec --drb manually thereafter says
that spork is working fine. What could be causing this?

Hi, have you tried to update spork & guard-spork (you are using an old version)?
