Is looks like libxml-namespacesupport-perl is not installed even though it is a dependency for libxml-sax-perl.

Is libxml-namespacesupport-perl installed? If yes, which version?

The same happened for me when upgrading from lucid to precise. I followed the idea reported in #296428 to reinstall libxml-namespacesupport-perl.

Here's a log of my actions. Since upgrading to precise, dpkg complained whenever I did anything:

$ sudo apt-get install (some-package-that-i-already-had)
(some-package-that-i-already-had) is already the newest version.
