Comment (by pcafstockf):

 The problem is that in the tarball, '**xattr.com.apple.provenance**' gets
 attached to the 'Mozilla-CA-20230801/README' file and the 'Mozilla-
 CA-20230801/lib/Mozilla' directory.\\
 System tar on older macOS do not know how to process these attributes.
 Indeed it seems that thanks to SIP, they can only be removed with great
 difficulty (https://eclecticlight.co/2023/03/13/ventura-has-changed-app-
 quarantine-with-a-new-xattr/).\\

 Unfortunately I need a to create a binary package that depends on p5
 -mozilla-ca which must be installable on a machine that may or may not
 have macports installed (e.g. Xcode may not be allowed), and so I have to
 set up a custom MacPorts install
 (https://guide.macports.org/#installing.macports.source.multiple).  \\
 This in turn makes the solution suggested by @snowflake a non-starter for
 me.

 I'm a long time MacPorts user and open source contributor, but a noob wrt
 creating / modifying ports, and have not yet figured out how the tarball
 itself gets created.\\
 If by "report the broken tarball issue to the developers", you mean file a
 GitHub issue, then I have now done that (https://github.com/libwww-perl
 /Mozilla-CA/issues/21).\\
 If you meant something else, could you please elaborate?

 If all else fails, some guidance on how I can fix this would be much
 appreciated.  I see from the original posting that I could create a local
 Portfile, override and modify it to use gnutar, but that really doesn't
 fix the problem for other users.
