[SciPy-User] SciPy+NumPy on 4 major linux distributions

[Ivo Maljevic]

For what is worth, I've updated liblapack and libblas to 3.2.1 under
openSUSE and numpy runs properly now.

It looks like Lev Givon is making similar progress with Mandriva, so the
situation is not as bad as I thought
initially.
