I like this one, although I guess you mean 'File::Spec::Functions'
instead of 'File::Spec'. 

This script is Debian-only, so full portability is not that important.
But if people strongly thinks otherwise, and 'File::Spec', from perl-base,
is properly available during all the upgrade, using it and
'File::Spec->catfile', like in attached patch, is another approach. 

This, regarding modifications to update-xmlcatalog in the short term. After
lenny this probably needs to be rewritten to work from postinst as Niko

However, that is only one part of the problem. The other part is what
happens if docbook-xml is unpacked before new xml-core is unpacked and
before perl-modules is configured. Seems that unpacking is done in
alphabetical order (and seems that people finds this problem in
docbook-xml because it goes early in the alphabetical list), and thus,
docbook-xml goes before xml-core (at least in normal apt-get runs, did
not try with dist-upgrade), and so prerm is run with old xml-core script,
failing. I wonder why this sometimes does not fail.

I am afraid the only way to make sure is following Niko proposal about
pre-dependencies on a newer and fixed xml-core.
