Comment (by Schamschula):

 I think I mistakenly uploaded a newer version of {{{patch-src-
 xar_internal.h.old.diff}}}. I've uploaded the correct version:
 https://github.com/macports/macports-
 ports/commit/a3d54e33fd4716dcfb060c320750d64b1050f533

 Note: for version 501 {{{xar_internal.h}}} has a line

 {{{xar_t xar_fdopen_digest_verify(int fd, int32_t flags, void
 *expected_toc_digest, size_t expected_toc_digest_len)
 API_AVAILABLE(macos(15.0));}}}

 Does that not mean that this is only available with the macOS 15 API, i.e.
 Xcode 16.x? However, it compiled fine with Xcode 15.4, after I patched the
 file.

 P.S. Yes, I'm aware that I can run older OS versions in virtual machines.
 I've done so in the past. It isn't a hardware issue (I have a collection
 of Macs going back to the original item) as much as a time issue: I'm
 teaching a double load this semester!
