Creating a sandbox evironment failed

I just tried creating a sandbox using sudo sandbox-clone-to-vm, but it failed.

The last output is this:
Done. Images are in /home/willem/intrepid/ubuntu-vm-hardy-amd64.
/proc/misc: No entry for device-mapper found
Is device-mapper driver missing from kernel?
Failure to communicate with kernel device-mapper driver.
/proc/misc: No entry for device-mapper found
Is device-mapper driver missing from kernel?
Failure to communicate with kernel device-mapper driver.
Incompatible libdevmapper 1.02.20 (2007-06-15)(compat) and kernel driver
device mapper prerequisites not met

Any idea on how to fix this?
I would really love to help out trying the update.
