I downloaded the antlr.zip and had a look.
In the ant-antlr3.jar there is the antlib.xml at your location.
If all classes are present you could try using the taskdef from that antlib
file:
<taskdef
name="ant-antlr3"
classname="org.apache.tools.ant.antlr.ANTLR3"
/>
and remove your xmlns declarations.
