The bundled node.fibers fails to load after deployment to a different server with the following error:
/home/ec2-user/bundle/server/node_modules/fibers/fiber
I had the same issue with Meteor 1.0.3.2 and Node 0.12.0. I had to downgrade to Node 0.10.31. This fixed the issue.
Remember all instructions are in the readme file in the bundle folder.
