Create Disk Image or Archive Error Message

I’m using Snow Leopard (10.6.2). I created an Automator workflow to create a .dmg file from a folder. I get an error message ‘The action “Create Disk Image or Archive” could not be loaded because it is not Universal.’

Do you have a Universal version of this action?

The action actually is Universal, but Automator on Snow Leopard wants it to support garbage collection. If you’d like to try a pre-release version, please contact me via e-mail.
