Try this:

Use this to see if the class is there: 
http://ant.apache.org/manual/CoreTasks/available.html

Then put the taskdef in a target, call that, and put an if="" attribute 
on that target to make it conditional.

Off the top of my head:

<!-- set have.JEMBuilder==true if the class is present-->
<available property="have.JEMBuilder"
            classname="com.ajile.tools.ant.JemBuilderTask">
   <classpath>
       <fileset dir="lib">
         <include name="**/*.jar"/>
       </fileset>
   </classpath>
</available>

<antcall target="load.JEMBuilder">
...

and make:

<target name="load.JEMBuilder" if="have.JEMBuilder">
   <taskdef name="JEMBuilder"
            classname="com.ajile.tools.ant.JemBuilderTask"/>
</target>
