No it isn't. What about next time you emerge ppp? Don't use
environment variables to alter emerge's behaviour. Instead, add

net-dialup/ppp activefilter

to /etc/portage/packages.use. That way, you'll always be sure it has
the correct USE flags.

capital punishment for stupidity, but why don't we just take the
safety labels off of everything and let the problem solve itself?
