haml error generating a spree store

[freefallr]

Hi there,
I've just installed spree and have followed the instructions only to
find the error message (pasted below) when I run script/server.

Is there a known fix for this, or am I missing something fundamental?
I've posted a list of installed gems below the webrick error message
if this helps..

I've found that doing a fresh install from here: http://spreecommerce.com/support/quick_start
works great
