Comment (by kencu):

 there are two different problems you are having, neither of which I’m
 having or most (but not all) are having. So MacPorts does not need fixing,
 probably — your installation, prossibly heavily modified it seems, needs
 fixing.

 So let’s only talk about one per ticket.

 1. the versioned sdk seems to have somehow crept back into some buildbot
 builds, I think. Dunno for sure yet if this is true, but the solutiion to
 that is to make sure the unversiond sdk is being used, and IF the build
 build does not use the unversioned sdk, revbump it. Done.

 2. you, and only younI believe, have messed up all the libgcc9, at least,
 symlinks. Or you don’t have libgcc and libgcc11 installed, or somehow
 you’ve messed up the system. The probable fix for THAT is going to be to
 have younunistsll MacPorts, clean out /opt/local until it is bare, and
 start over without touching any of libgcc* or the symlinks.

 So I suggest we talk only about problem 2 in this ticket, to keep it
 straight.
