You have to check the compiler's manual, it will *probably* say that when  
you are loading symbols (e.g. subroutines, functions) with the same name  
the *last* one to be loaded will be used.

it contains an optimized (for ibm) implementation of lapack, and fftw as  
well, if I remember correctly.
