thank you for your help. if i follow your advice, i don't link to the
atlas related libraries. is this meant to?
./usr/lib/libcblas.so.3
./usr/lib/libcblas.so.3.0
./usr/lib/atlas/libblas.so.3.0
./usr/lib/atlas/libblas.so.3
./usr/lib/liblapack_atlas.so.3.0
./usr/lib/liblapack_atlas.so.3
./usr/lib/atlas/liblapack.so.3.0
./usr/lib/atlas/liblapack.so.3
./usr/lib/libatlas.so.3.0
./usr/lib/libatlas.so.3
./usr/lib/libf77blas.so.3.0
./usr/lib/libf77blas.so.3
moreoever, i still have some linking problems:
make -k all

alternatively,
