There are a number of tools in Perl that will scan your code base and automatically generate a dependency list based on what it finds. The one I use is called Dist::Zilla (http://dzil.org/), and it automates the entire packaging and library release process. Again, this is how civilized languages work.

I'm sure Perl isn't unique here, of course.

That was completely unnecessary.

How else do you deal with all the import invocations in the source code files with outdated versions?

M4? Make + C preprocessor? Perl generating Perl? I tried to guess the least-absurd option for updating a library.

Please inform the rest of us what the standard tooling for handling this in the Perl community is.

Of course. A true Perl user has no need for sed, when there's "perl -pi -e".
