In f0f3b771f5cd8b403acf596ec5a67e44d832a7bc/macports-ports (master):

libwww: update to 5.4.2

• Patches are from FreeBSD [1]. Also switch the FreeBSD approach to specify OpenSSL path. It's simpler.
• Builds without ltconfig13 and ltmain13. Those are added 17 years ago [2]. I believe the issue has been fixed or is no longer relevant. Also, upstream ltmain is much newer than ltmain13.
• libwww-config.in.diff: not needed as the library order is fixed in 5.4.2.
• patch-configure.diff: there is no ac_tr_hdr in 5.4.2.

Note that some HTTPS sites are not working. For example,
webbot https://www.macports.org works but
webbot https://httpbin.org/ fails with "unable to get local
issuer certificate".

Closes: #58980
