mmh, given how green I am in the ubuntu world, you may well be right.
But my original question went before any linking happens, since I was
just posting the messages from numpy's system_info, which doesn't
attempt to link at anything, it just does a static filesystem
analysis.  So perhaps there is more than one issue here.

I'm just trying to clarify, from the given messages (which I found a
bit confusing) whether all the atlas/sse2 stuff is actually being
picked up or not, at least as far as numpy thinks it is.

Cheers,
