Ah, I see what it is. libintl is being pulled in by gnutls, which is
being pulled in by something else (gnutls is scheduled for emerge). To
find out what that something is, use emerge with -t

These dependency chains can get long and complex, so best is usually to
look at the whole thing and see exactly what is going on. Most often you
have something in world that is keyworded, or the current version is
still ~arch

You are right, that output doesn't make sense, possibly you have some
local config that is making it happen? Again -t will help sort out the
chain.

Something I find useful for these situations, take gnutls as an example:

grep -ir gnutls /etc/portage

finds everything I added to package.* and forgot about :-)
My make.conf is in /etc/portage, if yours is still in /etc/ you'll have
to grep that file as well
