Problems installing libc6

[Anders Brandt Petersen <anders@wizardry.dk>]

I can't seem to get libc6 to install. I keep getting this error:

Unpacking libc6 (from .../libc6_2.3.2.ds1-11_amd64.deb) ...
dpkg not recorded as installed, cannot check for epoch support !
dpkg: error processing 
/var/cache/apt/archives/libc6_2.3.2.ds1-11_amd64.deb (--unpack):
subprocess pre-installation script returned error exit status 1

I've have tried to reinstall dpkg (which actually is on the machine), 
but it gives me an error saying it predepends on libc6 :-(

Any tips to getting rid of this obstacle?

Thanks

Anders
