Current instructions for setting up kernel cross compilation setup

Hello:

Is there a tutorial somewhere which shows how to successfully build the Angstrom image(s) that have been released for the BBB?

I have done much googling, tried the various instructions found there, but all are outdated and no longer work with current linux releases, the instructions failed to note which releases they did work on either, so trying to load with old releases is not easy either.

I realize that trying to keep instructions for setting up a cross compilation setup current is akin to herding cats, but for those of us starting out it is very helpful to at least get the build environment working before we start coding.

It would be great to have instructions on how to build the kernel and filesystems for various releases that are available from Circuitco.

Thanks,
