I don't understand. When I looked into ebuild(1), I found "the installed files' checksums are recorded" which can be explained both ways but checksums from $PORTAGE_TMPDIR is more likely. -- Jan Sever

It makes the packages from $PORTAGE_TMPDIR and then installs from that package, when using buildpkg.
