There is a way to build from source... but it's always going to be one
that's a little
complicated and have high requirements (~6gb disk space, a long build time). It
may not be possible to build it on some machines.

I didn't forgot the second of these because it's not something I'd do or
recommend. It's a waste of time rebuilding gcc again. IcedTea doesn't
provide the AOT compilation that gcj does, which is used by other ebuilds.

well, the obvious solution is to depend on gcj-jdk directly, but even
whined about this when we used to do it.

Well, feel free to contribute and maintain one then.
