testdrive fails to install on karmic from ppa with virtualbox-3.2 installed

[MoLE]

Unfortunately it appears the ppa package for testdrive for karmic hasn't been updated to take into account the 3.2 release of virtualbox. After adding the ppa and attempting to install, it fails due to unsolvable dependencies.

I'm running karmic amd64 kernel.
