This means ANTLR 2 is not found for generating files. 
At present you need to install an ANTLR 2 (I use
2.7.7) jar in $ANT_HOME/lib as well as in ./lib. 
Also, stringtemplate.jar needs to be in ./lib.  I'm
going to send Ter an updated buildfile that 1) uses
the ANTLR 2 jar in ./lib for generation so it's not
necessary to add it both places (though it shouldn't
hurt) as well as provides warnings when ANTLR 2 or
stringtemplate is missing.

Matt
