Output of brew doctor

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: Homebrew's "sbin" was not found in your PATH but you have installed
formulae that put executables in /opt/homebrew/sbin.
Consider setting your PATH for example like so:
  echo 'export PATH="/opt/homebrew/sbin:$PATH"' >> ~/.zshrc

Description of issue

The first lines of the auxiliary scripts archive_color, code2color, sxw2txt and vim color coming with lesspipe do contain in the original sources on GitHub the line

#!/usr/bin/env perl
while my installed scripts are using

#!/opt/homebrew/opt/perl/bin/perl
As I do not have the homebrew perl installed, these scripts do not work and I get an error message:
zsh: /opt/homebrew/bin/archive_color: bad interpreter: /opt/homebrew/opt/perl/bin/perl: no such file or directory

Could that be fixed without requiring an additional installation of homebrew perl?

This is a brew bug for handling all bottles, i.e.

• Keg relocation doesn't account for uses_from_macos when replacing #!@@HOMEBREW_<language>@@ shebangs brew#20023 (stale closed)

---

brew will either need to save a record of dependency trees per platforms for all bottle, or re-calculate the dependency tree at install time.

Can see wrong info in manifest, e.g.

❯ brew fetch lesspipe

❯ jq '.manifests[0].annotations."sh.brew.tab" | fromjson' $(brew --cache)/lesspipe_bottle_manifest--2.20 | jq '.built_on.os'
"Linux"

❯ jq '.manifests[0].annotations."sh.brew.tab" | fromjson' $(brew --cache)/lesspipe_bottle_manifest--2.20 | jq '.runtime_dependencies | map(select(.full_name == "perl"))'
[
  {
    "full_name": "perl",
    "version": "5.40.2",
    "revision": 0,
    "bottle_rebuild": 0,

    "declared_directly": true
  }

I am not familiar with homebrew packaging, but the bug makes lesspipe less capable for users who do not have the homebrew perl installed (basically some colorizing of the output is missing if no external colorizer is installed). As the scripts in question require any perl (even 5.8. would do!) I do see several options

1. packaging the scripts as is (could be provided as a zip archive, which is unpacked in postinstall)
2. introducing an option in the build process that keeps certain files untouched
3. not requesting perl at all as the system version will do
4. requesting the homebrew perl as a dependency that has to be installed
