I took a good long look at Edillo and it's dependencies. There are actually three dependencies you need to build to make this work which may be where you ran into problems.
Edillo is designed for embedded devices, not for an ordinary desktop. MiniGUI would be used in lieu of a conventional DE on those devices. Can it work on Linux on an ordinary desktop/laptop? Yes, but there is extra overhead (you need MiniGUI built) and I'm not sure how well this would work. I've decided to pass on building this. There are enough lightweight browsers specifically designed for an ordinary X environment,
