It seems all the required jar files are not correctly set in your classpath.
Check $JBOSS_HOME/client/jbossall-client.jar is in your classpath
(this library contains javax.management.Attribute and javax.management.ObjectName)
and so on for other missing jars.
Hope this helped
I've dowloaded today release 3.2.6RC1 from the CVS repository.
From $MY_WORKSPACE/jboss-3.2/build/ I performed 'ant release-all' which builds a distribution for each archive type. It compiles OK including varia.
Just to check again, from $MY_WORKSPACE/jboss-3.2/varia I perfomed 'ant compile' and it built OK.
I used java 1.4 and ant 1.6.
I didn't build former 3.2.5 version but I think probably you had target depend problem.
