I wonder why you can't just build Haiku?
If you have already Linux or BeOS MAX running, that should not really
be a big problem (even x86-64 since Ingo's recent fs_shell changes
should work now).
x86-64 build didn't work a pair of weeks ago, I'll give it a try.

You can best contact Marcus Overhagen for this (marcus at overhagen dot
de) as he has written the current mixer and knows the domain best.
Ok, thanks, and sorry for time stealing with my personal problems :-)
