Hi, I have just committed a change so both Ant 1.6.5 and Ant 1.7.0. The only thing that is required is that you have ant in your $PATH. You can use --with-ant-home to set ANT_HOME still, but the default has been changed to /usr/share/ant. I have added a patch to the OpenJDK dir, that calls ant instead of ANT_HOME/bin/ant to start the langtools build. Lillian
