gnome uninstallable on Etch?

["Matthew T. Atkinson" <matthew@agrip.org.uk>]

Is anyone else unable to install gnome from Etch?  I get the following
error and am confident there are no packages being held back at my
request:

oberon:/home/matatk# aptitude install gnome
Reading Package Lists... Done
Building Dependency Tree
Reading extended state information
Initializing package states... Done
E: Unable to correct problems, you have held broken packages.
E: Unable to correct dependencies, some packages cannot be installed
E: Unable to resolve some dependencies!
Some packages had unmet dependencies.  This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

The following packages have unmet dependencies:
  gnome: Depends: gnome-desktop-environment (= 1:2.10.2.3) but it is not
installable
         Depends: gnome-office (= 1:2.10.2.3) but it is not installable
oberon:/home/matatk#


Thanks in advance for any information!
