Comment (by kencu):

 You should not be building anything other than {{{ld64 +ld64_xcode}}} on
 newer systems.

 {{{ld64 +ld64_xcode}}} doesn't build or need llvm, or need to be updated
 to ld64-530 -- it is just a few symlinks into xcode.

 If you presently have {{{ld64}}} installed with any variant OTHER than
 {{{ld64 +ld64_xcode}}} please do this:

 {{{
 sudo port -f uninstall ld64
 sudo port -v install ld64
 }}}

 and you SHOULD get {{{ld64 +ld64_xcode}}}

 if you do NOT get that, we have some work to do. Which we might well have
 to do.

 By the way, gcc10 will NOT build for arm64 at present. We do have a
 nearly-working fork of gcc-devel that is written by GCC's darwin lead that
 we are desperately trying to get working on Apple Silicon.

 At this moment, it builds neat, on the system, but does not build inside
 MacPort's infrastructure, so that is where we are with that at present.
