Possible to not require List::Util 1.55? #34

Is it possible to not require List::Util 1.55?

List::Util 1.55 is pretty new. My platform (debian 10) comes with List::Util 1.50.

Trying to build and then override the core List::Util seems a bit problematic

$ dh-make-perl --core-ok --build --cpan List::Util
[omit output]
$ dpkg --install libscalar-list-utils-perl_1.55-1_amd64.deb

Hey, it's neat to see someone else using this (even though it's not quite done yet).

Version 1.55 is needed for uniqint. But if you're using debian's package installer, they should have used the proper dependencies, and built a newer List::Util if this package required it. Have you filed a ticket with debian?

List::Util is part of the core perl package in debian. I'm sure the update will be in debian 11. But that's probably like 1+ years in the future.

Just thought I would ask.

Ok, I was confused how you could be installing this module on debian when the prerequisites weren't satisfied. If you are installing via a different mechanism, prerequisites will be satisfied differently - you can't expect debian to provide them. If you use a cpan client, it will install all the prerequisites for you; if you install manually (e.g. download the tarball and follow the INSTALL instructions) you will have to resolve them yourself.
