Comment (by murrayE):

 Replying to [comment:8 eborisch]:
 > Try re-installing mpich-default (uninstall & reinstall mpich-default
 which will then re-configure & build) after Xcode 15 installation. (mpich-
 default doesn't use buildbot packages, although the buildbot is still on
 Xcode 14 so it won't help currently anyway.)
 >
 > The issue is ld from Xcode 15 rejecting `-Wl,-commons,use_dylibs`. The
 configure script for mpich correctly detects this when Xcode 15's ld is
 used, but if you configure/install mpich under Xcode 14, and then upgrade
 Xcode, the compiler scripts (mpicc, mpicxx, etc.) will still have the
 offending switch.

 I DID install mpich and mpich-default using Xcode 15. (This was part of
 reinstalling all the ports I had after upgrading macOS to Sonoma and Xcode
 to version 15, and reinstalling MacPorts with the Sonoma version.
