This seems backwards. The .so.VERSION is copied in for me:

It is the .VERSION.MAJOR.MINOR that is symlinked and not copied in.

These symlinks do not show in `ldconfig -r` either so they are not going
to be copied by portmaster either

PKGNG also tracks shared libraries to detect reinstalls, but not the
symlinks:
