Redmine

HI all,

I am trying to install redmine on a winxp machine but I am stuck.

I followed the guide for installation, and I also issued the

gem install builder

because there were some problems with builder/xmlmarkup

now when I try to issue the command

rake db:migrate RAILS_ENV="production"

I got this error:

(in D:/downloads/FDM/Coding/redmine-0.8.0_RC1.tar/redmine-0.8.0_RC1)
rake aborted!
no such file to load -- active_support/core_ext/cgi/escape_skipping_slashes

and the trace :

D:/downloads/FDM/Coding/redmine-0.8.0_RC1.tar/redmine-0.8.0_RC1/rakefile:10
(See full trace by running task with --trace)
