[Djigzo users] Installing on Mac OS X - wrapper missing

Hi, I tried to install the tar.gz on Mac OS X, but the ant call fails with: init-wrapper: init: [echo] Trying to load 'wrapper.dist.Mac OS X.i386.properties' BUILD FAILED /Users/rainer/Projects/djigzo/djigzo/build.xml:96: The following error occurred while executing this line: /Users/rainer/Projects/djigzo/djigzo/wrapper/build.xml:12: wrapper.dist.tar cannot be determined. Does the property file 'wrapper.dist.Mac OS X.i386.properties' exist? As djigzo is advertized with "Djigzo runs on all systems that support Java and Postfix", I think it should be possible to make this work, and I want to try that. I'm a Java developer, and familiar with and, so a rough guide on what to modify in the ant files would be enough for me. So: what wrapper is this (original download), what is it used for, and is it possible to make djigzo work without it (e.g. directly starting any Java class)? Thanks Rainer Frey
