When running the ejb3 clustering tutorial against the installer's 'all" profile, I am receiving a TypeNotPresentException in my server.log

1. run the installer, select the "all" profile
2. build the ejb3 cluster tutorial "$ ant"
3 run the ejb3 cluster tutorial "$ ant run.stateless"

Ant exits with the following:
run.stateless:
[java] Exception in thread "main" javax.naming.NameNotFoundException: org.jboss.tutorial.clustering.bean.Session not bound
[java] at org.jnp.server.NamingServer.getBinding(NamingServer.java:491)
[java] at org.jnp.server.NamingServer.getBinding(NamingServer.java:499)
[java] at org.jnp.server.NamingServer.getObject(NamingServer.java:505)

I see this in my server.log
