It helped lots thanks! 
That augment task seems very useful, solves the problem perfectly. Never would have occurred
to me to use it.

Not sure about how you were suggesting to use the <tokens> resource collector though?

Here's what I came up with:

Property packages.rpm.build is set to a list of package names to build, minus version and
src.rpm extension and comma delimited.

    <fileset dir="${src}" id="rpmstobuild" />
    <!-- perform some manipulations using ant-contrib -->
    <antcontrib:for list="${packages.rpm.build}" param="rpmpkg">
      <sequential>
        <augment id="rpmstobuild">
          <include name="**/@{rpmpkg}*" />
        </augment>
      </sequential>
    </antcontrib:for>

    <apply executable="/usr/bin/rpmbuild" os="Linux" >
      <arg value="--rebuild" />
      <arg value="--define" />
      <arg value="_topdir ${rpm.topdir}" />
      <fileset refid="rpmstobuild" />
    </apply>

How would the <tokens> resource collector fit into this?

Obviously I've a little bit of work to do with adding a mapper to track the outputted rpms
to help stop the task re-running if it's not necessary.
