Code review comment for lp:~roederhr/revager/dmgbuild

I've tried the build script on Mac OS X Leopard. At first glance it seems to work very well, so you get a functional DMG file. The problem is that you get a usual DMG without the artwork. I don't know what exactly the problem is, but there is an error concerning Finder and the "RevAger" disk. Here you can see the output of Ant:
