I don't quite understand the question. Are you asking, "How do I find
out all the dependencies of the modules which I am 'use'-ing or
'require'-ing in my packages?
If so, and if you don't have many prerequisites, you can inspect the
Makefile.PLs of the modules you are requiring to see what they, in turn
I'm sure there's a more thorough way that someone on the list will
suggest, but I myself am averse to CPAN modules that sit on a mountain
of dependencies. Personally, I try to require only (a) modules
distributed with core; (b) modules that are verifiably pure Perl;
and/or (c) modules I myself have written. But that's a matter of
On Andy L's recommendation, I have installed Module::Corelist and its
associated utility, 'corelist', which tells when a core module became
core. This has been helpful in identifying which modules might work on
Perls older than 5.6 and which will not.
