OK. I figured this out myself, but I'll post the solution for posterity.
If you get "Could not create task of type: junit. Common
solutions are to use taskdef to declare your task, or, if this is an
optional task, to put the optional.jar in the lib directory of your ant
installation (ANT_HOME).", you might need the
jakarta-ant-1.3-optional.jar, which is available at
http://jakarta.apache.org/builds/ant/release/v1.3/bin/
. You might miss it if you download the rpms.
Next, pop open /usr/bin/ant, and add jakarta-ant-1.3-optional.jar and
junit.jar to the LOCALCLASSPATH
The optional.jar from the rpm does not have the classes you need in it.
Hope that saves someone else some work in the future.
