Yep, I think that's correct. However, in the Gentoo ebuilds there are the
DEPENDS and the RDEPENDS. Even if they are only runtime dependencies, it
might still be correct to put them in the ebuild on the RDEPEND clause.
But that's to be discussed with the Gentoo people, so I will not bother
you with that.

Well, then gtk-perl MUST be included as a dependency if the gtk and perl flags
are enabled, even if the these features are not going to be used on 99.99% of
the cases.

Yes, that's what I meant though I didn't express it correctly. True.
There are some Gentoo specific problems here. We would need two USE flags
to control if you are installing Gtk.pm and/or Gtk2.pm. The problem is that
there were the use flags gtk and gtk2 in the past, but now their usage is
discouraged (maybe forbidden, I am not sure), because gtk1 is being
phased out in portage, and the gtk flag should refer only to gtk2 unless
a given program doesn't support gtk2, but only gtk1. So, now there's only
one gtk use flag, which means that, if we want to abide the Gentoo policies,
that flag will push all that four deps that I listed, directly or indirectly.
There might be a number of possible solutions for this, but that's also
Gentoo stuff to be discussed with the Gentoo people.
Thanks so much for the input, it was quite helpful.
Cheers.
