dpkg missing binary `keep'

[Anders Breindahl <a.breindahl@post.cybercity.dk>]

Hi list,

I've run into a problem with Sid:

When upgrading the package lm-sensors I get this error:

le-skrewz:/home/skrewz# dpkg 
-i /var/cache/apt/archives/lm-sensors_2.8.8-1_i386.deb
(Reading database ... 93306 files and directories currently installed.)

dpkg: error while cleaning up:

Errors were encountered while processing:
 /var/cache/apt/archives/lm-sensors_2.8.8-1_i386.deb

I have been poking around, and haven't been able to find a solution. I have 
tried manually editing /var/modutils/0keep to not call `keep', and I have 
tried various combinations of purging, reinstalling and removing the packages 
lm-sensors and modutils.
If `keep' is indeed an executable, I would guess that I could work around the 
problem by temporarily placing it in my path, running the `apt-get upgrade', 
which bugs me at the moment, and returning the original state of the 
system... But I am unable to find a such executable binary.

Now I ask the list for help. Have you got any suggestions for me?

Kind regards, and thanks in advance, Anders Breindahl.
