Comment (by physicsbeany):

 @cjoines051073, I had some reason for needing libgcc-devel, but I don't
 recall the decision-making process. I just looked to see what depended on
 it, and I got the following:

 {{{
 > port dependents libgcc-devel

 OpenBLAS depends on libgcc-devel
 gcc12 depends on libgcc-devel
 gsl depends on libgcc-devel
 libgcc11 depends on libgcc-devel
 openmpi-default depends on libgcc-devel
 }}}

 I just tried nuking those five ports -- plus their own dependencies -- and
 doing a clean reinstall of a top-level port I know I wanted, openmpi. This
 looked like it was going to avoid libgcc-devel, using libgcc12 instead,
 but that failed too (different error):


 {{{

 I'm attaching that new log here.
