Problem upgrading to Rails 3.1 using capistrano

Rails
1

I’ve upgraded a Rails 3.0 app to Rails 3.1. It’s working fine on my
development Windows PC using Webrick / ruby 1.8.7.

I tried to deploy using Capistrano to a server using Passenger/nginx/
REE, but am getting this error :

Any pointers ?

Seems to have been fixed overnight by new bundler version 1.0.17 : see
