libpam-usb pmount missing command

Binary package hint: libpam-usb

gutsy package, version 0.4.0-1ubuntu1

I got this on console:
"
* pam_usb v0.4.0
* Authentication request for user "tr" (login)
* Device "MyDevice" is connected (good).
* Performing one time pad verification...
* Probing volume (this could take a while)...
sd 5:0:0:0: [sdb] Assuming drive cache: write through
sd 5:0:0:0: [sdb] Assuming drive cache: write through
sh: pmount: not found
* Mount failed
* Access denied.

"

This happens if you plug in the usb stick and try to login on a console before gnome automounter mounts the drive.

With pmount installed:
- you don't get the error above
- it works in this tricky situation too

Solution: libpam-usb or pamusb-tools should depend on pmount
