Comment (by kencu):

 The binary links only to libSystem.B.dylib:

 {{{
 otool -L
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_sysutils_kubectl/kubectl-1.17/work/destroot/opt/local/bin/kubectl1.17
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_sysutils_kubectl/kubectl-1.17/work/destroot/opt/local/bin/kubectl1.17:
         /usr/lib/libSystem.B.dylib (compatibility version 0.0.0, current
 version 0.0.0)
 }}}

 So there is no easy way around this --

 interposing] a library might work, but it's not practical.

 So the port might as well mark all the broken systems as unsupported for
 now, "known_fail yes", etc, etc, and close this.
