>Description:
        
pkgsrc from 16-September-2013 fails to complete bootstrap on Darwin 9.8.0 
(Leopard 10.5.8) on 64 bit PowerPC G5 (--abi 64):

Note that removing "--abi 64" fixes this.
>How-To-Repeat:
        
On fully up to date PowerPC G5 Leopard system with latest (last) Xcode 
installed, cvs checkout pkgsrc and attempt to execute bootstrap.
>Fix:
        

>Unformatted:
 build from bootstrap on Darwin 9.8.0 (Leopard) when target is ppc64
