OpenWrt Version

OpenWrt 25.12.5 r33051-f5dae5ece4 / LuCI openwrt-25.12 branch 26.187.49110~99464ec

OpenWrt Target/Subtarget

ramips/mt7621

Steps to Reproduce

When I try to use these modules in Perl there are not available:
use Getopt::Std;
use Text::CharWidth;

Actual Behaviour

The modules Getopt::Std and Text::CharWidth are not installed. When I try to use them I receive this:

Can't locate Getopt/Std.pm in @INC (you may need to install the Getopt::Std module) (@INC entries checked: /usr/lib/perl5/5.40)

Can't locate Text/CharWidth.pm in @INC (you may need to install the Text::CharWidth module) (@INC entries checked: /usr/lib/perl5/5.40)

I then went down the rabbit-hole trying to add the modules via cpan:
perl -MCPAN -e 'shell'
install Getopt::Std

I have expanded storage setup on /dev/sda and a 2GB swapfile file on /dev/sda3.
When I try to add the modules from within the perl/cpan shell it fails and eventually crashes the router.

Anyhow, shouldn't these modules be part of the default Perl installation or at least be available via "apk add perlbase-??????"?

Not sure how to address this issue, is it a bug report or a feature request or both?

Confirmation Checklist

• The package is maintained in this repository.
• I understand that issues related to the base OpenWrt repository or LuCI repository will be closed.
• I am reporting an issue for OpenWrt, not an unsupported fork.

Start by checking OpenWrt's Perl package definitions and available package names for Getopt::Std and Text::CharWidth on the ramips/mt7621 target. Compare the default Perl installation with separately installable packages, then verify that both modules can be installed and loaded without using CPAN on the router.
