Comment (by Dave-Allured):

 I checked source code and port files for Mumps 5.6.2.  **-commons** is not
 specified or needed anywhere by Mumps, because Mumps does not use fortran
 COMMON or EQUIVALENCE anywhere.  (Reference:  Xcode docs for "ld".)

 Meanwhile, it looks like **-commons** is being injected here from
 **/opt/local/bin/mpicc-mpich-mp**.  **-commons** is a known problem with
 the Sonoma/Xcode 15.0 linker.  So check **mpicc-mpich** for **-commons**
 problems.  It is possible that there is already an open ticket for this.
 That is all I have time for right now.

 Oh yeah, I agree that @catap's **-ld_classic** suggestion may be a viable
 temporary workaround.  That is also tricky because the previous linker
 will choke if it gets that flag unintentionally.
