It turns out the lintian lab is accessible at lintian.d.o but doesn't
have unpacked source packages.

So I did it myself and grepped through 3394 unpacked source packages
(those that build depend on perl, or produce binary packages that depend,
recommend, or suggest perl).

Results of grepping for "use module" and "require module" follow. I've put
the raw data available at
 http://people.debian.org/~ntyni/perl/deprecated-modules.txt.gz
in case someone wants to conduct a more comprehensive search.

I had a quick look through these and removed a few false positives,
but there may still be some left.

	libdata-treedumper-perl
	libemail-abstract-perl
	libmasonx-interp-withcallbacks-perl
	libparams-callbackrequest-perl
	libtemplate-declare-perl

Note that this doesn't catch packages that need a separate unpack step,
which is why libcgi-application-extra-plugin-bundle-perl from
the earlier list is missing.

Preliminary conclusion: we're going to need at least three of the four
modules packaged, and I'm inclined to throw in Pod::Plainer as well
for the sake of completeness although nothing in Debian uses it.
