Errno::ENOENT in User sessionsController#new No such file or directory - getcwd

I cloned an existing git repo and get that error when I try to use
script/server and view the application on a mongrel server. I can
still access the models in script/console.



Someone may suggest an answer from this limited data but I think the
full stack trace might be helpful. Have a look at it yourself first
and try and see what is wrong. If it gives a line number in
user_sessions_controller where it has failed have a look at the code.
