Hokay, I gave it a shot and it didn't work. Basically, I stopped syncing my local repo around the time when CM6.1.1 was released, so there's a lot of stuff missing. I lack the time, will and bandwidth to do a full sync I'm afraid. (Really bad internet here, I need to do something about that)
@BlaY0, "make recoveryimage" pushes out a .img file, can't you just post that? Given that you have to do it anyway to convert it to a fakeflash zip it doesn't seem to me to be too much to ask. Just my 2 small-units-of-money
Now, it occurs to me that there might be a way to do this without syncing the whole CM tree. If there is, and someone knows about it, my ears are wide open and I'm ready to learn
