Re manual step...  From /usr/sbin/postinstall - this comment speaks
about an embedded awk script that does this work:

#       The implementation supports removing obsolete major libraries
#       if the awk variable AllLibs is set, although there is no way to
#       enable that in the enclosing shell function as this time.

We should probably use an environment variable to supply that
assignment on the awk invocation (-v AllLibs=1) so that you don't have
to copy and edit it.

POSTINSTALL_OBSOLETE_MAJOR_VERIONS_YES_I_KNOW_WHAT_I_AM_DOING or
something.
