Redmine

I recently installed Ruby, Gem, Rails, and then Redmine on my Redhat Linux Enterprise server. I'm struggling to get redmine to run correctly. I posted in another thread and received advice recommending the installation of mongrel, which I tried.

If I clear cookies in my browser and load the page, the initial page displays perfectly. Clicking on any page returns the 500 error. if I clear my cookies, I can view the inital page again, but the pattern repeats: I can view any page and then clicking a link returns another 500 error.

Thanks in advance for any help.

Here's what Mongrel shows in response to the request:
