persistence configuration errors?

Someone please help me keep my sanity!  I started getting an error after
deleting my webapp dir and doing an ant clean on my project.

After starting the container, and accessing just the main static page, i
get this in the system.log file:
ERROR   2004-04-12 14:13:47.047   [system.command]
(/org.apache.avalon.fortress.util.FortressCommandFailureHandler.handleCommandFailure(FortressCommandFailureHandler.java:57)): Could not prepare ComponentHandler for: org.keel.services.persist.defaultpersist.DefaultPersistentFactory
org.apache.avalon.framework.configuration.ConfigurationException: No
attribute named "name" is associated with the configuration element
"schema" at Merged [layer:
file:/usr/local/src/jakarta-tomcat-5.0.19/webapps/occa/WEB-INF/keel/server/conf/svc-persist-base/system.xconf:17:45, base: file:/usr/local/src/jakarta-tomcat-5.0.19/webapps/occa/WEB-INF/keel/server/conf/svc-persist-default/system.xconf:58:45]
        at
org.apache.avalon.framework.configuration.DefaultConfiguration.getAttribute(DefaultConfiguration.java:279)

which corresponds to this line in the conf files:
<schema id="component-security">

which eventually results in this at the client:
            null, null, Unable to provide implementation for
        org.keel.services.authentication.AuthenticationManager/*
    (Key='org.keel.services.authentication.AuthenticationManager/*')

I can not find any errors in my build output, nor in any other log
files, tomcat or keel/server.

this comes after a fresh checkout of cvs early last week.  I can't
imagine this is enough information for anyone to figure what the heck is
going on, but I don't know what else to include, and am at my wits end
(it didn't take long either!)

thanks in advance
