I posted this way back in 2005 (the date is incorrect, I migrated from Drupal to Wordpress in 2007) and only actually used Cantera for a month or so. So I can't provide any useful advice going forward unfortunately and your mileage may vary if you aren't running MacOSX 10.4 like I was. But it shows how important it is to share the details of your solution to replace out of date instructions like this page.
