I guess the problem is due to
/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.5/../../../../x86_64-suse-linux/bin/ld: 
cannot find -lgcc_s
/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.5/../../../../x86_64-suse-linux/bin/ld: 
cannot find -lgcc_s

locate libgcc_s yields

/lib64/libgcc_s.so.1
/lib/libgcc_s.so.1
/usr/lib64/gcc/x86_64-suse-linux/4.1.2/libgcc_s.so

I am confused by the fact that lapack_lite.so is involved.
I thought that it is obsolete if ATLAS is installed.
Am I missing something ?
I have build BLAS and LAPACK with g77. gfortran seems to 
be
the new standard. Is that correct ?
Should I build BLAS and LAPACK with gfortran ?
