What part of the build is dependent on Ant-1.4.1?  The only thing
I've found is that if you don't have JUnit-3.8.1 in ANT_HOME/lib then the
build fails even if you aren't running tests.  For instance, I just
ran "ant clean" and got this...

BUILD FAILED
file:D:/myclasses/Repository/Enhydra/XMLC_DSF_2003-03-12/xmlc/libraries/util/mod
ules/junitTivano/build.xml:79: taskdef class
org.apache.tools.ant.taskdefs.optio
nal.junit.JUnitTask cannot be found

However, with that jar in ANT_HOME/lib, I build XMLC just fine with
Ant-1.5.2.  Where is the Ant-1.4.1 dependency?  I suggest
getting rid of the extra modules such as JUnit.  The problem is
classloading.  Since most current Ant releases come with
"optional.jar" in ANT_HOME/lib, the optional task require their
dependencies at the same level in the classloader hierarchy.  In
this case <junit> requires junit.jar to be in the same
classloader.  The parent classloader can't see junit libraries to
load in a child classloader.  Really, I'd get rid of Ant and Junit
as modules.  Actually, You might think of getting rid of gnu-regexp
as a module.  We haven't modified that at all, have we?

Well, Ant can filter copy stuff just fine.  I haven't looked at the
source for the strings, but are they something like @some_token@ ? 
That is pretty simple to do in Ant.  In fact, if you look at the
xmlc tomcat demo build.xml, there is lots of that going on.
