After changing this line in php5-sapi-r2.eclass from:

inherit eutils confutils libtool

to

inherit eutils confutils libtool flag-o-matic

Portage started spitting out a QA Notice:

QA Notice: ECLASS '$ECLASS' inherited illegally in '$CATEGORY/$PN'

which you can find in /usr/lib/portage/bin/ebuild.sh around line 1422.

There’s no valid reason why my change violates Gentoo’s QA policies. I haven’t managed to find any official documentation about this, and Ciaran’s doc doesn’t yet have much about it, so I thought I’d spend the evening digging into it in the hope that it’ll prove useful to others.

If you’re reading this on Planet Gentoo, click the link at the top of this posting to see the full article.

And if you don’t want to read it all, the solution to this problem is to run:

ebuild foo.ebuild depend

to rebuild Portage’s metacache, which makes the warning go away.
