when installing amazon module (4.2) on drupal (4.2) i get an ungly error, causing page to step rendering when block is enabled:
Fatal error: Unknown function: drupal_url() in /var/www/html/myblog/modules/amazon.module on line 402

before installing i dropped two old amazon tables and did insert the new amazone.mysal again.

anyone else seen this or know how to solve this?
