Comment (by ronf):

 Sadly, after spending a couple of hours attempting to reinstall all the
 ports again from scratch, I'm seeing the same error. Everything else
 installs just fine, but py310-cython is still complaining about egg_info
 and the various other config options above. So, there's something outside
 of whatever MacPorts is writing to that's causing this, but I have no idea
 why it isn't affecting any of the other ports.
