Comment (by kencu):

 If you look at the python311 Portfile, it has this added:


 https://github.com/macports/macports-
 ports/blob/b89544daea33be9f48ea990fa763ddc45b2a11cd/lang/python311/Portfile#L47

 {{{
 if {${configure.build_arch} in "ppc ppc64"} {
     # https://trac.macports.org/ticket/66483
     configure.ldflags-append -Wl,-read_only_relocs,suppress
     # G3 builds fail without this flag, as converting a static library
     # to dynamic using -all_load inadvertently sets the arch to ppc7400
     configure.ldflags-append -Wl,-force_cpusubtype_ALL
 }
 }}}


 so most likely, that block, probably all of it, but at least the
 {{{force_cpusubtype_ALL}}} part of it, needs to be added to the python312
 Portfile.

 You would open them with this:

 {{{
 sudo port port clean python312
 bbedit `port file python311`
 bbedit `port file python312`
 }}}

 and then copy the block from the python311 Portfile, and add it to the
 python312 Portfile.

 Hopefully that is all that will be needed.
