Preparing Schema: Installing Dashboard

[Gmoney]

When I run this command::

rake RAILS_ENV=production db:migrate

I get this error:

Could not find rack (~> 1.1.0) amongst [actionmailer-3.2.2,
actionpack-3.2.2, activemodel-3.2.2, activerecord-3.2.2,

I have rack-1.4.1 gem installed. What am I missu=ing here? I am
attemptin gto install on Red hat 6. I installed ruby-enterprise-1.8.7
from source and pulled the puppet-dashboard-1.2.0 tarball down to my
RH^ server.

Error says it all:    rack (~> 1.1.0)

You have 1.4.1, which I believe is pulled in as a dependency, you need 1.1.0.

gem install rack -v 1.1.0

gem uninstall rack -v 1.4.1
