Another possible solution would be distribute binary packages to
users via PORTAGE_BINHOST. The user can simply set something like
PORTAGE_BINHOST="http://tinderbox.dev.gentoo.org/default-linux/x86"
in /etc/make.conf. Since DEPEND is ignored for binary packages, and
circular RDEPEND doesn't block installation, the circular
dependencies won't necessarily be an problem. The emerge --pretend
output shows that emerge will go ahead and install those packages
despite the circular RDEPEND:

These are the packages that would be merged, in order:
