The portage bug that I referred to was with new-style virtuals. It
was due to complications in the code related to this bug:

  http://bugs.gentoo.org/show_bug.cgi?id=141118

Due to that code, with <sys-apps/portage-2.1.7 you could get some
strange results with USE deps inside new-style virtuals. Nobody ever
reported a bug though, so maybe it's not very noticeable.
