Well, you only need the -search_paths_first for java I think, and you  
don't need to specify -mcpu=970 (unless you want to of course), and  
you don't need to specify the target_board for the check. If you  
installed gmp into /usr/local or /usr/ you wouldn't need that line  
either. I've got a 4-way fat version I've been using for explicitly  
that purpose. Otherwise, unfortunately, you do need the rest since  
darwin is unlikely to return the 64-bit versions of the processors for  
config.guess any time in the near future.

thanks for all of the testing help. Is this helping your app build as  
well now?
