Over the past few days, I've been trying to dive in and help out in the F15 effort by resubmitting failed builds and helping to identify key packages that are failing to build. I've posted my list of packages at http://openetherpad.org/Fedora-ARM-jsmith, and will try to keep it updated, at least in the short term. The way I created my list was to take the "critical path" packages from F15 (on x86_64, because that's what I had handy), and the list of failed builds in F15 on ARM Koji over the last week, and anything that was in both lists went onto my list. It's a rough list at best, but it's a start :-)
The good news is, most of the packages rebuilt just fine. There are still a dozen or so packages that need extra attention, so please look at my list and feel free to dive in and start helping. (Please mark on the website that you're working on a particular package, so that we don't step on each others' toes.)
