Redmine

I've been tasked to install redmine by my supervisor to assist in bug tracking over a few projects. I have little to no experience working with Ruby or Redmine so if I seem vague, I apologize. I'll supply any additional information requested

I've been following this guide http://www.redmine.org/projects/redmine/wiki/HowTo_Install_Redmine_in_a_sub-URI_on_Windows_with_Apache

I am using Mysql 5.1
Ruby 1.87
Rails Version 2.3.5
Windows XP

Following the guide I've installed and configured Ruby, it's rails version and the mongrel gem. I've also installed Apache 2.2 and mysql.

My problem is when I attempt to migrate the db with the following command

rake db:migrate

I see the following errors

C:\Webserver\Redmine>rake db:migrate --trace
(in C:/Webserver/Redmine)
** Invoke db:migrate (first_time)

I've attempted to search for an answer to no avail. Any help would be appreciated.
