And it won't, because I am afraid the Ubuntu atlas package is broken in
8.10... They use the gfortran  ABI, but they built the fortran wrappers
with g77, according to ATL_buildinfo.

I would strongly advise using atlas on Ubuntu 8.10 until this bug is
solved: it means any numpy/scipy code using linear algebra is
potentially broken (segfault, wrong results).

cheers,

David
