Redmine

Hello all,

I'm relatively new to this, and trying to install this plugin:

http://www.redmine.org/boards/3/topics/11986?r=12290#message-12290

but I can't make it work. I'm using Bitnami Redmine 0.8.4-1 on Mac OSX (although I'm going to do the same on a Linux system). Here's what I did, after copying the plugin folder into /Applications/redmine-0.8.4-1/apps/redmine/vendor/plugins/:

$ cd /Applications/redmine-0.8.4-1/
$ use_redmine
$ cd /Applications/redmine-0.8.4-1/apps/redmine/vendor/plugins/
$ gem install spreadsheet
$ rake db:migrate_plugins RAILS_ENV=production
$ /Applications/redmine-0.8.4-1/ctlscript.sh restart

but the plugin still doesn't appear. Anyone see anything obvious that I'm doing wrong? Is that the correct folder to place the plugin in on a Mac? Thanks in advance.
