 > I was able to build by modifying the Portfile to add "-ld_classic" to
 the LDFLAGS.  Xcode 15 switched the default linker to Apple's "prime"
 version.  "-ld_classic" forces it to use the same one as Xcode 14 (and
 earlier).  This is probably a temporary solution until someone more
 knowledgeable figures out what's going on with the new linker.

 I am a little surprised this worked, as these flags are not passed
 (directly) to the linker by via the compiler I would have though the
 option should have been

 -Wl,-ld_classic
