Hi,
The CSV writer that I mentioned in the other thread comes with the standard Ruby library, so you should not need to install anything to use that.

If you have plugins to install, bring up a command shell, change directory to your RAILS_ROOT, then run:
$ script/plugin install <plugin>
do:
$ script/plugin --help
for more information on the plugin mananger.
