I am going with this one.
Did this first:
$ curl -O http://svn.macosforge.org/repository/darwinbuild/trunk/plists/9A581.plist

Changed this line:
RC_ARCHS=ppc # at the top (`grep i386 9A581.plist'  returns 132  
results though but I pretend not to see, or should I? My understanding  
is that's why we are doing it this way and not the quick/dirty way(?))

<http://svn.macosforge.org/repository/darwinbuild/trunk/README> says  
something about RC_ppc but I can't find it.

I found some other interesting stuff here too:
What would happen if I removed individual projects from 9A581.plist?  
Can I finally get rid of AppleTalk and Chess?  How about AppleRAID?  
(and where is bluetooth?)

What if I changed source_sites from
	http://src.macosforge.org/Projects/
		to
	http://www.opensource.apple.com/darwinsource/Current/
Would then darwinbuild do what it's supposed to do but build from  
Current source? How about binary_sites?

Thanks
