[antlr-interest] Rebuilding Antlr 3.0.1

[HJ]

I was able to satisfy the dependency by installing the ant-optional package in Ubuntu.

As a sidenote, the build process also requires Junit to be installed.

I still can't build 3.0.1 (errors below), but the HEAD (development) tarball downloaded yesterday builds just fine, and that's good enough for me.

Cheers,
