Comment (by butter71):

 ''xcode 15 / sonoma / x86''

 ''port variant: -x11 +gpl2''

 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.


 {{{
 + configure.ldflags-append \
 +                     -ld_classic
 }}}
