exiftool is missing IO::Uncompress::Brotli

[cmahnke]

brew gist-logs <formula> link OR brew config AND brew doctor output

brew gist-logs exiftool
Error: No logs.

Verification

• My brew doctor output says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.
• I searched for recent similar issues at https://github.com/Homebrew/homebrew-core/issues?q=is%3Aissue and found no duplicates.

What were you trying to do (and why)?

Running exiftool against a JXL image:

 exiftool Flamingo/jxl/front.jxl

What happened (include all command output)?

Warning : Install IO::Uncompress::Brotli to decode Brotli-compressed metadata

What did you expect to happen?

JXL metadata displayed

Notes

Note that the verification doesn't really apply, since a missing dependency in the formula

This is a follow up of the discussion https://github.com/orgs/Homebrew/discussions/5013 and in parts of #192273:

Currently exiftool cant work with JXL metadata out of the box. This is due to missing IO::Uncompress::Brotli, this is an optional perl dependency.

We (the impacted users from the discussion) now propose one of two mitigation possibilities:

• Either include IO::Uncompress::Brotli as part of the installation
• Avoid using system perl and add a dependency to Homebre perl and allow using modules from this installation
