Right, thanks. Note that sys-fs/udev is not on my system, the conflict
occurs because portage wants to emerge it. I am trying to downgrade the
virtual udev.
I tried your suggestion as follows
* quickpkg'ed
sys-app/systemd virtual/udev sys-app/gentoo-system-integration
* unmerged all three
* merged the desired virtual/udev version with --nodeps
(it wouldn't work without --nodeps)
* tried to emerge the desired versions of the other two
(without using --nodeps)
This last step fails because it seems (assuming I am reading the emerge
tree output correctly, see below) that dev-libs/lubusbx-1.0.17:1 requires
virtual/udev-206.
But I don't see that version dependence in the ebuild. Moreover this is
the only version of libusbx in the tree so (again assuming I am reading
the tree correctly) this says that gnome 3.6 requires
virtual/udev-206-r2, which seems strange. Indeed, canek has said that
gnome has trouble with systemd-206 (which virtual/udev-206 would bring
it).
So I did the emerge -K you suggested and am back where I started.
Any help would be appreciated.

I am hoping not to have to do that (or emerge --nodeps).

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.
For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

NOTE: The --autounmask-keep-masks option will prevent emerge
from creating package.unmask or ** keyword changes.
Use --autounmask-write to write changes to config files (honoring
CONFIG_PROTECT). Carefully examine the list of proposed changes,
paying special attention to mask or keyword changes that may expose
experimental or unstable packages.
