For example every time you upgrade tcl you get:

 * Messages for package dev-lang/tcl-8.4.15:

 *
 * If you're upgrading from tcl-8.3, you must recompile the other
 * packages on your system that link with tcl after the upgrade
 * completes.  To perform this action, please run revdep-rebuild
 * in package app-portage/gentoolkit.
 * If you have dev-lang/tk and dev-tcltk/tclx installed you should
 * upgrade them before this recompilation, too,
 *
 * GNU info directory index is up-to-date.

So I propose we add some variables like

INSTALLATION_TYPE="reinstall|upgrade"
for upgrade PREVIOUS_VERSION="8.3"

This way the ebuild could detect where we are upgrading from and only give the messages when one is really upgrading.

ive resorted to "has_version" in pkg* functions in the past which sucks and can be unreliable ... having the package manager tell the ebuild the transition state would be nice

EAPI 4 has been approved by the council.
