Setting up git commit hook for Redmine

Question

I am trying to migrate the setup here at the office from SVN to Git and am setting up Redmine as the host for our projects and issue management (Currently we use a version of Gforge + SVN). I should preface by saying that I'm an embedded C software developer by day and have basically zero experience with Rails or web apps, but I like trying new things so I volunteered to set up the project management tools which will take us into the future.

I have Redmine setup and am using Gitolite as the Git repo manager. Additionally, I am using the ericpaulbishop/redmine_git_hosting plugin to facilitate automatic public ssh key pushing to Gitolite and automatic repo creation when we register a new project. Everything seems to work except the repo view within the project does not keep track of the changesets. (The "History" is just empty, although when you view the files, it does show the latest version correctly)

I copied the post-receive hook from the plugin's contrib directory to the .gitolite/ common hooks, but again I know little about Ruby and how these gitolite hooks work so I don't know how to debug this. I notice there are log messages and things in the hook, but I have no idea where those are printed, etc...

I even tried the Howto on the Redmine wiki, HowTo setup automatic refresh of repositories in Redmine on commit:

#!/bin/sh

curl "http://<redmine url>/sys/fetch_changesets?key=<your service key>"

Any ideas on where I start debugging? I've been able to resolve every problem up to this point, but I'm a little stuck now. The plugin doesn't make it obvious how this is supposed to work, and to be honest, I'm not even sure if this is a problem with Redmine not reading the repo correctly (or at all), or gitolite not communicating as Redmine expects, etc...
