On my hardened ~amd64 machine I see the following error when merging scipy.

I'm not really sure what's happening here and am willing to track this down. I have blas-reference from science overlay installed. I also use sage-on-gentoo overlay (just to name anything that could be connected).

Comment 2 François Bissey 2012-02-20 00:12:29 UTC

I got this too. I hit bug #386269 first. After unmerging ATLAS I ended up with this. scipy with python 3.2 seem to be bent down to want atlas and the site.cfg is not doing the trick.
The mere presence of atlas on the system even if not eselected trigger numpy to link to clapack (at least numpy-1.5.1 I think).

And yes sage-on-gentoo is connected it's our being stuck with numpy-1.5.1 problem if I am not mistaken.
If you move to numpy 1.6.x do you still hit this?

After upgrading to numpy-1.6.1-r1 scipy-0.10.0 merges fine.
