[ale] Any debian experts? How do I forcibly remove something that isn't installed.

[Jim]

I tried to install a package that needed a newer version of libc.  It 
didn't install but now something appears to be hosed.  No matter what I 
try to install, remove etc, I get the following message.

Removing libapache2-mod-ifier ...
This module is already disabled, or does not exist!
dpkg: error processing libapache2-mod-ifier (--remove):
 subprocess post-removal script returned error exit status 1
Errors were encountered while processing:
 libapache2-mod-ifier
E: Sub-process /usr/bin/dpkg returned an error code (1)

I've tried using --purge --force-all, --remove --force-all on dpkg but 
it says it isn't there.  The message above came from an apt-get install 
foo command.

How do I fix the database, any idea?

Thanks,
Jim.
