Zyzzyva also has a user mailing list, which you can join at http://groups.yahoo.com/group/zyzzyva-users/. If you are building Zyzzyva from source code, you will need the Qt4 library, available from http://www.trolltech.com/download/opensource.html. After Qt4 is installed, the following steps should be sufficient to build Zyzzyva: qmake make On Mac OS X, instead of running qmake and make directly, you should run installer/create-macx-bundle.sh instead. This will create an executable bundle under installer/macosx. Please email Michael Thelen with questions, comments, patches, or large cash donations. Happy hacking!
