You're right; I forgot that equery and its equivalents work by default
on installed packages (although sometimes that's what you need, so it's
still good to know). I don't know how 'pkgspec' works either (though
I've never looked into it, so that's no surprise), so even though it
does suggest that you could search the Portage tree of not-installed
packages to see what PacKaGe SPECifies a particular file, I don't know
how precisely to use equery to do so.

I find it most useful to go to the Debian package search tool
 ( http://www.debian.org/distrib/packages -- "search the contents of
packages") on the (extremely) rare occasion that I need to know what
(not currently installed) package provides a particular file or library.
The package names are often not quite the same, but usually close enough
that you can find the correct package on packages.gentoo.org. Putting
the exact filename into Google works too; you'll get a whole list of
where one or two similarly-named rpm's, deb files and slack packages are
located, and then you most likely know the name of the application you
want to search on packages.gentoo.org.
