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

[Chris Colbert]

What I would like to see is a distribution build numpy and scipy with
threaded atlas support.

As it stands currently, Ubuntu "has atlas support", but its not
threaded, and the packages are broken...

Until that happens, I'll be rolling my own numpy and scipy from source.

Cheers,

Chris
