I forgot: another possibility is to use gfortran instead of g77, but you 
will have to recompile everything (you cannot really mix  g77 and 
gfortran code together), including BLAS/LAPACK. For FC6, I remember that 
gfortran is the default ABI, so this is anyway the best choice, but I am 
not sure for FC5.
