 This is exactly what I observed as described in #60893, so I don't think
 it's just the reporter (or me).

 Replying to [comment:11 kencu]:
 > There was another user a few weeks ago on Catalina who also had the
 wrong ld64 installed, but his was defaulting properly, so easily fixed,
 whereas yours, for some reason, is not.

 Not sure if I'm the user in question, because I manually installed `ld64
 +ld64_xcode`—it did not eventually default properly.

 The other thing that might've been unusual about my setup is that I have
 only the command line tools, not the full Xcode, so `$xcodeversion` is
 `none` for me.

 I would expect `$xcodeversion` to be influenced using `xcode-select`
 (likely a better way of switching Xcode versions than with links), if it
 isn't already; and for MacPorts in general to not rely on Xcode being at
 /Applications/Xcode.app.
