Missing Module in CPAN

roho has asked for the wisdom of the Perl Monks concerning the following question:

The module "Net::LocalCfg" is missing from CPAN. I did some research and found the following (I am using Strawberry Perl 5.24.1 on Windows 10):

1. Core module "C:\Strawberry\perl\lib\Net\Config.pm" requires module "Net::LocalCfg".
2. Module "Net::LocalCfg" does not exist in CPAN.

It appears to me that "Net::LocalCfg" needs to be reinstated in CPAN, or removed as a required module in "Net::Config". The docs for "Net::Config" say that "Net::Config" inherits from "Net::LocalCfg".

I sent an email to the current maintainer of "Net::Config" (Steve Shay) over a month ago, but have not heard anything in reply. Any other suggestions how to resolve the issue? Thanks.

Net::LocalCfg seems to be a an optional dependency, so Net::Config should work without it. It doesn't exist in CPAN, and I doubt it has ever existed - at least, there are no traces of it in the Wayback Machine or Google Search. Maybe it's a class the user is supposed to create? I don't see why creating the parent class would be beneficial, but maybe someone else knows? `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]

Was actually curious so went poking and I think it's a bug / mis-implemented feature that won't work as is now (presuming I'm reading the docs right and my empirical messing around was done correctly). According to the documentation it's so that you can (paraphrasing) define class methods which will override the defaults for things like `requires_firewall` (which looks like the only specific method at any rate). But since the `Net::Config` would be a child of the putative `Net::LocalCfg` class then its (`Net::Config`) local version would override the parent's (`Net::LocalCfg`) implementation. To do what it says on the tin you'd need to have your own subclass of `Net::Config` with the special behavior therein so that when you call the class method on that it'd do the right thing and find your custom overridden version.

> Maybe it's a class the user is supposed to create? This seems to be a reasonable assumption for something called "local config". Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply]

Thank you all for your input. The reason I asked this question was that perl2exe listed it as a missing module, which I initially thought was causing the executable created by perl2exe to fail. Further research revealed that this missing module had no affect on the executable created by perl2exe, and I located the source of the problem elsewhere. Once again, thanks for the input.
