   | Building NetBSD 11.99.1 as of "Wed Aug 27 08:42:01 PDT 2025" on macOS 15.4.1 host.
   | >Description:
   | At some point, some DES man pages were renamed, and the change varies only by case.  On a fresh "release" build from a host with a case-insensitive/case-preserving file system (e.g. macOS APFS), this causes the obsolete file check to remove the freshly-installed-with-new-name man pages, but subsequently blow up in the "checkflist" stage.

   | The obsolete check probably should be smarter about deleting items.  A basic lookup of the file is insufficient -- the directory entry for the file should probably be examined and a case-sensitive verification of the file name performed.

 This is a subset of the issue I reported in toolchain/57463.
 
 I've not thought of a good workaround for "DESTDIR on a case insenstive"
 filesystem yet :|
