Do we mean:

  because the bootstrap default now uses mksh, we will consider pkgsrc
  broken if a package fails to build with SIP and mksh, but won't
  consider it a bug if it fails with SIP and some other shell?

that seems fine, if so, but it would be good to be clear on it (and
update README.MacOSX as well).
