Here I am... :)  via command line is easy:

-lib dir-or-jar

There is also
which might be of use but still results in the same
ultimate problem of adding THAT library instead of
another.  On ant-dev we have a dead discussion of a
similar task that could be shipped with Ant; I'm about
to resurrect that thread one last time and we'll see
what can be done for 1.7, if anything.

You said "if not," but I'll address this anyway:  You
can <java
classname="org.apache.tools.ant.launch.Launcher"> or
<java classname="org.apache.tools.ant.Main">, but you
are on your own to keep up with the appropriate
command-line parameters.  :(  Not ideal IMO.
