drupal_get_form

I'm trying to install this against a 4.6 Civicspace install rather than against Drupal HEAD and I'm getting:

PHP Fatal error: Call to undefined function drupal_get_form() in /home/wlp/csl/modules/actions/actions.module on line 126

drupal_get_form() seems to be a 4.7 phenomena. How can I get either a 4.6 release or a cvs version that works with either 4.6 or 4.7.

Right now I just get a blank page and an error in the apache logs.
