Hi David,

Sorry it took so long to get back to you.  The problem appears to be that 
Galaxy is using a version of Paste from your site-packages rather than the egg 
bundled with Galaxy.  A quick solution to this would be to set up a virtualenv 
as described in the production server documentation and run Galaxy under that 
interpreter.
