Comment (by kencu):

 The flag is coming in from another port, as above, mpich-default, in this
 exact file:
 {{{
 /opt/local/bin/mpicc-mpich-mp
 }}}

 here:
 {{{
 final_ldflags="
 -Wl,-syslibroot,/Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk
 -Wl,-commons,use_dylibs"
 }}}

 There is some kind of configuration problem with mpich -- I built it on
 Sonoma with Xcode 15 and it still had this flag embedded, even though the
 linker rejects it.

 Someone will sort that out, but for now you can just remove that flag from
 the ascii textfile driver, changing that line to this:

 {{{
 final_ldflags="
 -Wl,-syslibroot,/Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk"
 }}}

 and all is well:

 {{{
 % port -v installed scotch
