The issue is known and appears to be a problem with a specific version  
of Apple's compilers generating incorrect ppc code. It goes away when  
you update to Apple's gcc 4.2 (or probably also when you revert to  
older compilers, although I didn't test that route specifically).

However, I'm surprised that 2.5.1 would work *if* you had exactly the  
same setup, because the dbeta source code didn't change since 2.5.1 at  
all. Are you 100% sure that you had exactly the same compiler versions  
as now?
