What is the exact configure command you're running? I suspect that  
your problem is a 32-bit vs 64-bit mismatch, because SL changed the  
gcc default to 64-bit whereas the gfortran default is 32-bit, so you  
have to make sure your archs match (depending on which you actually  
want to build) - ideally you should specify -arch for all compilers  
(as the CRAN binary does - also see the FAQ).
