I wonder if debian atlas package has the same problem as on recent Ubuntu.

there is no need to do this I think: it should work out of the box
without any site.cfg (the point is that it would make it easier to
change which atlas is loaded at runtime for further debugging of the

No, the f77 refers to the fortran 77 dialect, not the compiler.
What I would try is first install libatlas-base (or whatever it is
called on sid), i.e. the non sse version, and compare test output with
both sse2/nosse (e.g. using LD_LIBRARY_PATH to point to /usr/lib so
that the nosse is loaded, you can check using ldd which one is loaded
