Yes-ish. We don't have a lot of osx-specific code, and unless
there's plans to make lilypad-osx fancier, we don't really need
any more code.

You're more in touch with that side than me.

I think a single PPC machine is enough.

This is the single most important thing -- not just for osx, but
for all binary building. However, AFAIK there is no help
available for GUB.
I can give quick answers to GUB questions that I know the answer
to, but I'm not willing to spend a great deal of time debugging
it. I spent 100+ hours doing that in the fall of 2009; I consider
that I've paid my dues.

Yes-ish. It works on my desktop when I boot into lilydev 10.04.
It does not work on my desktop in my usual ubuntu 11.10, which
means that I can't use my desktop for anything important while GUB
Some developers can run GUB on lilydev. Others can't. No pattern
has emerged in this yet, nor has anybody wanted to get into it.
My initial guess is that it would take me 2-10 hours to get GUB to
compile on ubuntu 11.10. To estimate how long it would take
somebody else, multiply those numbers by whatever factor you think
That's not very encouraging, but *somebody* needs to do this at
some point. I'm not going to keep ubuntu 10.04 around forever.

All platforms, plus the official regression test comparisons, plus
the official documentation.

I doubt it; apple doesn't like their OSes inside VMs (IIRC it's
actually expressedly forbidden in their EULA), but even if that
was possible, it would likely only be osx-x86 running on top of

Focus your efforts on GUB. And yes, everybody who's gotten the
latest make bootstrap error has given up.

As long as you don't give up, you *will* succeed eventually. What
"eventually" means depends on your existing knowledge of unix
build systems and how much other aid you get.
But again: this problem isn't going to go away unless somebody
tackles it. GUB is the weakest link in our development chain.
Bringing it under control would be a great step forward.
