After apt-get -f install

[Kurt Petersen <kurt@ache.dk>]

Hi

After deborphan I deleted a library. The error message recommended
"apt-get -f install".

After that I got a lot of 

...
dpkg: error processing mon (--configure):
 subprocess post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of postfix-mysql:
 postfix-mysql depends on postfix; however:
  Package postfix is not configured yet.
 postfix-mysql depends on postfix (= 2.3.8-2); however:
  Package postfix is not configured yet.
...

These packages ARE configured and work fine.

How to get rid of these messages when updating the system with
apt-get?

Thanks!
Kurt
