[one-users] occi-server fails to start

[Daniel Molina]

Hi,

There is a compatibility problem with last versions of sinatra and
rack using ruby 1.8.7.

You can fix this issue in two ways:
1. Upgrading ruby to 1.9
2. Downgrading rack version to 1.2.0:
# gem uninstall rack
Select gem to uninstall:
 1. rack-1.0.0
 2. rack-1.0.1
 3. rack-1.2.1
 4. All versions
> 4
# gem install rack --version '1.2.0'
Successfully installed rack-1.2.0
1 gem installed

Hope this helps
