Ok, thanks.  I'm cc-ing the apt maintainers in case they have
ideas for debugging this.

apt maintainers: when Sophoklis tried a dist-upgrade, he got the
following result:

	# apt-get update ; apt-get dist-upgrade
	...
	You might want to run 'apt-get -f install' to correct these.
	The following packages have unmet dependencies:
	 zlib1g-dbg : Depends: zlib1g (= 1:1.2.7.dfsg-4) but 1:1.2.7.dfsg-7 is installed
	 zlib1g-dev : Depends: zlib1g (= 1:1.2.7.dfsg-4) but 1:1.2.7.dfsg-7 is installed
	E: Unmet dependencies. Try using -f.

zlib1g-dev and zlib1g are "Architecture: any" binary packages from
the same source package, and zlib1g-dev 1:1.2.7.dfsg-7 from the
archive depends on zlib1g 1:1.2.7.dfsg-7, not -4.  Any suggestions
to help track this down?

Sophoklis: /var/log/apt/term.log, /var/log/dpkg.log, and "apt-cache
policy zlib1g zlib1g-dev" may help piece the story together.

Sorry for the fuss.
