Problem running Mongrel with Rails3 and Ruby 1.8.7

Question

I am running a linux instance. My question is the same as LoadError running Mongrel with Rails3 and Ruby 1.9.2 except for the fact that I am running Ruby 1.8.7 and I am using Linux.

Here is the contents of the mongrel_cluster.log:

I am at a loss on how to fix this.

Can someone help please? TIA

What does gem listreturns?

How does your Gemfile looks like?

Did you try reinstalling Rails?

Consider using RVM and a Gemset for each project so that you can isolate gem conflicts.
