Hi, all —
The existing instructions on the wiki are for "Attitude Adjustment", and I wanted to build "Barrier Breaker". I also wanted to update the OS X instructions, at least, since they're both out-of-date and reliant on MacPorts rather than Homebrew.
The build completed without any apparent problems on both platforms. I haven't tried actually flashing the image onto a device
yet — I only have the one at the moment — but I see no reason that it shouldn't work, it appears to have done all the correct things.
At any rate, I've put this all together in a blog posting. I'd certainly appreciate any corrections or feedback, and I hope it's of some use to folks who want to play with this stuff...
