Removing evolution but leave gnome intact?

[keitho@strucktower.com]

I realize it is not necessary, but if possible I'd like to remove evolution.

This is what I have tried so far:

# aptitude unmarkauto gnome-control-center evolution-data-server
# aptitude unmarkauto libedataserverui1.2-11 capplets-data
# aptitude unmarkauto evolution-data-server-common
# aptitude unmarkauto gnome-session gnome-panel gnome-applets

# aptitude -s -R remove --purge evolution-data-server /
  evolution-data-server-common libedataserverui1.2-11 /
  gnome-control-center: gnome-panel: gnome-applets: gnome-session:

gets me:

The following packages will be REMOVED:
  evolution-data-server evolution-data-server-common libedataserverui1.2-11
0 packages upgraded, 0 newly installed, 3 to remove and 443 not upgraded.
Need to get 0 B of archives. After unpacking 10.8 MB will be freed.
The following packages have unmet dependencies:
  gnome-control-center: Depends: evolution-data-server but it is not going
to be installed.
  gnome-panel: Depends: libedataserverui1.2-11 (>= 2.32.2) but it is not
going to be installed.
The following actions will resolve these dependencies:

     Remove the following packages:
1)     gnome-applets
2)     gnome-control-center
3)     gnome-panel
4)     gnome-session

Accept this solution? [Y/n/q/?]

I've seen some discussion mentioning the keep-all instruction, but I don't
know exactly how to use it or even if it would help.

Ideas?

I'm using Wheezy with Gnome Version: 2.30.2

Thanks,
Keith
