Comment (by cjones051073):

 I am also running into this, although the error seems to be slightly
 different for me. The important part would appear to be

 {{{

 /_Users_chris_Projects_MacPorts_ports_python_py-

 clang: error: linker command failed with exit code 1 (use -v to see
 invocation)
 }}}

 I strongly suspect this is just the Xcode 15 linker issue again, having
 trouble with the openblas dylib which was created in part with GCC.

 I've tried a few ways to get the build to go back to the legacy liker,
 which should work with something like

 {{{
 if {${os.platform} eq "darwin" && ${os.major} >= 22} {
     if { [vercmp ${xcodeversion} >= 15.0] || [vercmp ${xcodecltversion} >=
 15.0] } {
         # On macOS13 and newer ensure the 'legacy' linker is used as GCC
 currently has problems
         # with the new default linker in Xcode 15. See e.g.
         # https://developer.apple.com/documentation/xcode-release-
 notes/xcode-15-release-notes#Linking
         # https://discussions.apple.com/thread/255137447
         # https://developer.apple.com/forums/thread/737707
         # https://github.com/Homebrew/homebrew-core/issues/145991
         configure.ldflags-append  -Wl,-ld_classic
     }
 }
 }}}

 but this port does not seem to be respecting the above flags.
