eclipse - problem installing new features

[AG <alang@bigpond.net.au>]

I cannot install any new features in eclipse, when I use the eclipse
update-manager I am getting the following error;

 Unable to retrieve remote reference
"http://download.eclipse.org/callisto/releases/features/org.apache.commons_logging.feature_1.0.4.v200606152055--0842282-233879.jar";. [Server returned HTTP response code: "404 Not Found" for URL: http://download.eclipse.org/callisto/releases/features/org.apache.commons_logging.feature_1.0.4.v200606152055--0842282-233879.jar.]

It will happily discover the available features but if I try to install
any I get message similar to the above. It happens whatever site or
mirror I use.

running deb testing

eclipse Version: 3.1.2
Build id: M20060118-1600 (Debian version: 3.1.2-2)

Any ideas to fix would be appeciated.
