I know.

The problem is that if you don't have qt3 support, Portage tells you
to enable qt3support for _one_ of those packages.  If you do exactly
what portage tells you (enable it for that one package), then portage
will complain and tell you to disable it for that package.  At least
that's what always seemed to happen for me.
