Comment 2 for bug 237317

I'm on amd64 hardy as well:
lool@fox:~$ dpkg --print-architecture
amd64
lool@fox:~$ lsb_release -sir
Ubuntu
8.04
lool@fox:~$ dpkg -l libcupsys2 | grep libcups
ii libcupsys2 1.3.7-1ubuntu3 Common UNIX Printing System(tm) - libs
lool@fox:~$ ls -ld /usr/share/doc/*cups*

The problem is with the symlink itself:
lool@fox:~$ ls -l /usr/share/doc/libcupsys2/changelog.gz
lrwxrwxrwx 1 root root 26 2008-04-28 12:08 /usr/share/doc/libcupsys2/changelog.gz -> ../libcupsys2/changelog.gz

debsums cupsys | grep -v OK$ doesn't return any related problem
