What's wrong with my builds

As I've said here before, this is my first RPM Fusion package, so I could be doing something wrong. But I don't know what. My package ProjectX was recently approved and created in CVS. Now I'm trying to build. I started builds last Tuesday. When I checked them yesterday evening, they were still marked as building, but when I checked the builder status only the ppc builder was available. So I assumed something went wrong on the builder side. But I didn't have time to look more at it then. This morning I had got mails that the builds had failed. Not strange if the build host went down or something. So I tried another build. This one finished in four minutes. But it also failed. And when I try to look at the logs to see what went wrong (http://buildsys.rpmfusion.org/logs/fedora-development-rpmfusion_free/8016...) I don't see any logs at all. There is a SRPM package there, but no logs in neither the i686 nor the x86_64 subdirectories. Shouldn't it be? Am I doing something wrong? If so what could that be? Or is this another error on the build host side? Something I should file a bugzilla about? My build command was simply "make build" in the devel branch of my package.
