Actually, no. And that is why the gtk flags need changing. :)
current setup.
gtk ~= gtk support AND fall back to gtk v1 support.
gtk2 ~= use gtk v2 support in preference to v1 if available.
There is no way to state, "I want v2, and _only_ v2" without resorting
to a package.mask'ing of gtk-1*.

my scheme- gtk == *any* version, the user doesn't care.
gtk{1,2,3} == use that version.
So... if you had USE="gtk2 and gtk3", ebuilds would use v3 if
possible, otherwise v2. No gtk v1.
If you had USE="gtk gtk2", you prefer gtk v2., but will use what is
available (any version).

The current scheme sucks for those who want a gtk v2 only system. How
do you specify gtk v2 only under the current system using _just_ use
flags? You don't. :)
