Ah-ha, it only appears if you only call bootstrap-rap.sh (without
stage1).  But never mind.

I understand now.  If you call stage1 explicitly, you are doing a manual
bootstrap.

  https://wiki.gentoo.org/wiki/Project:Prefix/Manual_Bootstrap

The PATH should be set up manually before calling the script:

  export EPREFIX=<somewhere you want>
  export PATH="$EPREFIX/usr/bin:$EPREFIX/bin:$EPREFIX/tmp/usr/bin:$EPREFIX/tmp/bin:/usr/bin:/bin"

Yours,
